Long Carbon Fiber Reinforced PPS
High-performance thermoplastic composites can replace metals. Although PEEK is regarded as the benchmark for engineering performance, reinforced PPS offers a truly cost-effective alternative.
The demand for engineering thermoplastics such as PC and high-performance thermoplastics like PEEK is steadily increasing in industrial applications. These materials, when produced in the form of 3D printing filaments, offer lightweight alternatives to metals for industries such as aerospace and energy.
By incorporating reinforcements, the properties of these high-performance plastics can be further enhanced. For example, the addition of chopped carbon fibers improves both strength and stiffness. Such reinforcements can be applied not only to low- and mid-range engineering plastics but also to high-performance thermoplastics. As long as the 3D printer nozzle can handle abrasive materials, these composites can be printed as easily as standard thermoplastics.
However, a major drawback of high-performance composites such as reinforced PEEK is the high cost of the required 3D printing hardware. These materials demand extremely high extrusion and chamber temperatures, and the equipment capable of meeting these requirements often costs six figures—undermining one of the key advantages of plastic 3D printing: cost efficiency.
This article explores carbon fiber reinforced PPS as an alternative that delivers performance comparable to metals and PEEK, while offering significant advantages in temperature requirements and overall cost.
Introduction to PPS
What is PPS?
Polyphenylene sulfide (PPS) is a semi-crystalline thermoplastic commonly classified as a high-performance polymer, alongside materials such as PEEK and PEI. It is widely used in machining, mold manufacturing, and additive manufacturing due to its excellent mechanical strength, superior heat resistance compared to standard and engineering thermoplastics, and inherent flame retardancy.
One of the most remarkable properties of PPS is its outstanding chemical resistance. It can withstand a wide range of acids, bases, and solvents, and even shows partial resistance to strong oxidizing agents under certain conditions. However, for particularly aggressive oxidizers such as chlorine dioxide, additional coatings or linings may be required for protection.
With its exceptional performance and more affordable cost compared to PEEK, PPS has found broad applications across various industries. Its mechanical and chemical durability make it ideal for automotive, energy, and chemical processing sectors, while its flame-retardant and self-extinguishing characteristics make it a preferred material for electrical and electronic components, such as surface-mount devices (SMT), motor housings, and transistor encapsulations.
Beyond being an outstanding thermoplastic, PPS is also a reliable replacement for metals such as steel and aluminum. Its thermal stability and chemical resistance enable it to perform effectively in harsh chemical environments, offering strong protection against corrosion and automotive fluids.
PPS as a Composite Material Solution
Reinforced PPS
To improve its strength and rigidity, PPS is often reinforced with chopped carbon fibers or glass fibers, resulting in composite materials with enhanced performance. In fact, PPS is more commonly available in a filled form rather than unfilled.
Researchers have noted that “the addition of carbon fibers significantly enhances the mechanical properties, tribological behavior, post-fire structural integrity, as well as the electrical and thermal conductivity of PPS blends and composites.”

Introduction
PEEK (Polyether Ether Ketone) is a linear aromatic high-performance polymer with repeating units of –O–Ph–O–C(=O)–Ph– in its molecular backbone. It is a semi-crystalline thermoplastic and a high-performance specialty engineering plastic with numerous advantages over other specialty plastics.
PEEK has a melting point of 334 °C, a softening point of 168 °C, and a tensile strength of 132–148 MPa. It exhibits excellent mechanical properties, high-temperature resistance up to 260 °C, good self-lubrication, chemical resistance, flame retardancy, peel resistance, wear resistance, and radiation resistance. It can be used in high-end mechanical, nuclear, and aerospace applications. It can also serve as a high-temperature structural material and electrical insulation material, or be compounded with glass fiber or carbon fiber to produce reinforced materials. PEEK is synthesized through a condensation reaction of 4,4′-difluorobenzophenone and hydroquinone in the presence of an alkali metal carbonate, using diphenyl sulfone as a solvent.
Properties of PEEK Resin
PEEK plastic raw materials are aromatic, crystalline thermoplastic polymers with a melting point of 334 °C. They exhibit high mechanical strength, high-temperature resistance, impact resistance, flame retardancy, acid and alkali resistance, hydrolysis resistance, wear resistance, fatigue resistance, radiation resistance, and excellent electrical properties.
High-Temperature Resistance
PEEK resin features a high melting point (334 °C) and a glass transition temperature of 143 °C, with a continuous use temperature of 260 °C. Grades reinforced with 30% glass fiber or carbon fiber have a heat deflection temperature as high as 316 °C.
Mechanical Properties
PEEK resin offers excellent toughness and rigidity. Its fatigue resistance under alternating stress is comparable to that of metal alloys.
Flame Retardancy
Flammability is measured according to UL94 standards, which involves igniting a vertically mounted sample and recording the time taken for it to self-extinguish. PEEK achieves UL94 V-0, the highest flame-retardant rating.
Dimensional Stability
PEEK exhibits outstanding dimensional stability under changing environmental conditions such as temperature and humidity, making it suitable for applications requiring high precision.
PEEK has low injection molding shrinkage, enabling tighter dimensional tolerances than general plastics.
Its low thermal expansion coefficient ensures minimal dimensional changes due to temperature fluctuations.
PEEK maintains stable dimensions under usage and storage, as polymer chain movement is minimal.
Its hydrolysis resistance prevents dimensional changes caused by moisture absorption, unlike common plastics like nylon.
Electrical Insulation
PEEK exhibits excellent electrical insulation properties over a wide temperature range, with low dielectric loss even at high frequencies.
Radiation and Peel Resistance
PEEK resin has good radiation and peel resistance, making it suitable for specialized electrical wires. It can be used in sterilizers and wireless verification systems, providing performance comparable to stainless steel.
Exceptional Performance
- Outstanding high-temperature performance: continuous use up to 250–260 °C, short-term exposure up to 300 °C.
- Very high stiffness, tensile and compressive strength, and impact resistance.
- Excellent flame retardancy: inherent flame retardancy, low smoke and low toxicity.
- Resistant to almost all organic and inorganic chemicals (except highly corrosive agents like fuming sulfuric acid, nitric acid, or dichloromethane).
- High dielectric strength and excellent insulation properties.
- Superior wear resistance and low friction coefficient.
Applications
As a high-performance semi-crystalline aromatic engineering plastic, PEEK can replace metals and ceramics in many demanding applications. Its high temperature resistance, chemical stability, mechanical properties, dimensional stability, low thermal expansion, wear resistance, and self-lubricating properties make it ideal for aerospace, mechanical, petroleum, chemical, nuclear power, and railway industries. Even under 200 °C steam, its tensile strength, mass, and appearance remain stable. It has excellent fatigue resistance under high alternating stress, long-term load-bearing capability, flame retardancy, self-extinguishing property, and environmentally friendly combustion (halogen-free, UL94 V-0, oxygen index 24–35).
PEEK is only soluble in concentrated sulfuric acid and nitric acid; otherwise, it is chemically stable, though insufficiently crystallized PEEK may develop cracks in certain solvents like chlorinated hydrocarbons.
Processing
PEEK can be processed via injection molding, extrusion, blow molding, or compression molding. For small-batch or prototype PEEK components, machining from rods or sheets is preferred. Machining should use carbide or diamond tools due to PEEK's wear resistance. Pre-annealing the material can relieve residual stresses, and post-machining stress-relief treatment is recommended to prevent local stress buildup during processing.
Current Uses
PEEK is widely used in electrical insulation (wires, flexible PCBs), mechanical components, chemical equipment, nuclear engineering, oilfield connectors, valves, heat-resistant or corrosion-resistant coatings, and in sterilizers and wireless verification systems, sometimes serving as a stainless steel alternative. Its exceptional combination of properties continues to make it a high-demand material across multiple advanced industries, including aerospace, automotive, electronics, medical, and food processing.
How does a pile of loose ceramic powder transform into a final product with complex shapes and precise structures? All of this is thanks to a key manufacturing step: forming.
Today, we will clearly explain three main ceramic forming methods, exploring their working principles, advantages, disadvantages, and typical applications.
1.Dry Pressing
This is the simplest and most common method, very suitable for the mass production of simple-shaped parts.
Working Principle: Ceramic powder mixed with a small amount of binder is filled into a metal mold. Then, high pressure is applied via upper and lower punches to compact the powder into a dense "green body".
Advantages:
High Efficiency: High degree of automation and fast production speed.
Uniform Dimensions: Excellent product consistency.
Low Cost: Suitable for large-scale production.
Disadvantages:
Difficulty in manufacturing complex shapes (e.g., parts with side holes, thin walls).
High mold cost.
Possible uneven density in the green body.
Typical Applications: Ceramic seal rings, gaskets, substrates, bricks, tiles, etc.
2. Isostatic Pressing
Isostatic pressing was developed to solve the density uniformity issues of dry pressing. It uses a liquid or gas as the pressure-transmitting medium to compress the powder uniformly from all directions.
Working Principle: Ceramic powder is loaded into a flexible rubber or plastic mold, which is sealed and placed into a high-pressure vessel. Pressure is applied via a high-pressure pump, uniformly compacting the powder.
Advantages:
Uniform Density: The properties of the green body are consistent in all directions, which is key for manufacturing high-performance ceramics.
Good Shape Capability: Can produce parts with relatively complex shapes.
Disadvantages:
Large equipment investment.
Production cycle is longer than dry pressing.
Relatively low dimensional accuracy, often requiring subsequent machining.
Typical Applications: Large crucibles, high-voltage electrical insulators, spark plugs, high-performance structural components.
3. Injection Molding
If you need to manufacture ceramic parts with highly complex 3D geometries, similar to metal or plastic parts, injection molding makes this possible.
Working Principle: A large amount of ceramic powder is mixed with a thermoplastic binder and plasticized upon heating. It is then injected into a sealed mold cavity using a screw. After cooling and solidifying, it is demolded to obtain the "green body". Subsequent debinding processes are required to remove the binder before sintering.
Advantages:
Extremely high shape complexity and dimensional accuracy.
Automated production, high efficiency.
Good product consistency.
Disadvantages:
The debinding process is very slow and prone to causing defects.
High cost of molds and equipment.
High raw material cost.
Typical Applications: Micro ceramic gears, engine turbine rotors, medical surgical tools, electronic packaging components, etc.

In the grand landscape of modern electronics, ceramic substrates, though often operating behind the scenes, play an indispensable and critical role. From high-frequency signal transmission in 5G base stations, to motor controllers in new energy vehicles, and further to the core packaging layers of power semiconductors, ceramic substrates are consistently stationed at the heart of electronic components. They silently shoulder the dual mission of acting as the "Thermal Backbone" and "Insulation Guardian."
Taking 5G base stations as an example, their operation generates significant heat. If this heat is not dissipated promptly, device performance can drastically degrade, potentially leading to failures. Leveraging their exceptional thermal conductivity, ceramic substrates can rapidly transfer heat away, ensuring stable base station operation. Within the motor controllers of new energy vehicles, ceramic substrates must not only endure high-temperature environments but also withstand the challenges of high voltage and high current. Their superior insulation properties and mechanical strength provide reliable assurance for the efficient operation of the motors.
According to forecasts from authoritative institutions, the global ceramic substrate market is projected to soar from USD 1.13 billion in 2022 to USD 4.15 billion in 2029, achieving a remarkable compound annual growth rate (CAGR) of 18.23%.

Today, with the continuous increase in the power density of electronic devices, heat dissipation has become one of the key bottlenecks restricting technological development. Traditional thermal interface materials are gradually unable to meet the demands of efficient heat dissipation. Nitride ceramic fillers, especially aluminum nitride (AlN), hexagonal boron nitride (h-BN), and silicon nitride (β-Si₃N₄), are emerging as new research and application focuses due to their outstanding thermal conductivity and comprehensive physical properties.
Aluminum nitride (AlN) is regarded as an ideal material for the next generation of heat dissipation substrates and electronic device packaging due to its excellent thermal conductivity (theoretical thermal conductivity of 320 W·m⁻¹·K⁻¹), reliable electrical insulation, low dielectric constant and dielectric loss, as well as a coefficient of thermal expansion (CTE, 4.5 × 10⁻⁶ °C⁻¹) that matches that of silicon.
Hexagonal boron nitride (h-BN), with its wide bandgap (5.2 eV), high thermal conductivity (theoretical thermal conductivity of 2000 W·m⁻¹·K⁻¹), and low density (2.3 g·cm⁻³), has a hexagonal ring network structure similar to graphene and is often referred to as "white graphene." Coupled with its excellent lubricity and chemical stability, it has gradually become a major focus in the field of thermal interface materials.
Polymer composites using BN as a nano-filler can simultaneously achieve high thermal conductivity, low CTE, and high electrical resistance, meeting the urgent demands of new high-efficiency thermal management materials. Additionally, β-Si₃N₄ as a filler facilitates the formation of a particle network, enhancing thermal conductivity while maintaining good mechanical and thermodynamic stability.
Nitride ceramic fillers exhibit exceptional intrinsic thermal conductivity, making them a key research direction in the laboratory development of ultra-high thermal conductivity thermal interface materials. However, the preparation of nitrides is relatively challenging and costly, particularly for nitride fillers with high application value and specific shapes, such as spherical AlN, BN nanosheets/nanotubes, and β-Si₃N₄ whiskers. Achieving low-cost, efficient, and industrial-scale mass production remains one of the important research topics.
