PPS-LCF40 | 40% Long Carbon Fiber Reinforced Polyphenylene Sulfide
PPS-LCF40 is an ultra high performance, semi crystalline thermoplastic composite reinforced with 40% long carbon fiber, engineered for maximum stiffness, strength, and dimensional stability in the most demanding mechanical, thermal, and chemical environments. Its high fiber loading delivers metal like structural performance, while preserving PPS’s intrinsic thermal stability and chemical resistance.
Compared to lower fiber content grades like PPS-LCF20 and PPS-LCF30, PPS-LCF40 offers superior flexural and tensile strength, creep resistance, and load retention, making it the material of choice for precision structural parts subjected to thermal cycling, high stress, and aggressive chemicals.
Core Performance Highlights
Mechanical Properties
Carbon Fiber Content: 40% (long chopped fibers, highly oriented during molding)
Tensile Strength: ≥ 190–200 MPa
Flexural Modulus: ~17–18 GPa
Elongation at Break: ~0.7–1.0%
Notched Izod Impact: ~40–50 J/m
→ With significantly higher fiber volume, PPS-LCF40 provides extreme stiffness and strength, ideal for metal replacement in high load, weight sensitive applications.
Thermal Resistance
Heat Deflection Temperature (HDT): ≥ 270 °C
Continuous Use Temperature: Up to 240 °C
→ Delivers long term structural integrity under continuous thermal stress, with excellent dimensional control and low creep—even in high heat operating cycles.
Environmental & Chemical Durability
Moisture Absorption: <0.02% — virtually impervious to humidity
Chemical Resistance: Excellent — resists degradation from fuels, oils, acids, bases, and industrial solvents
→ Ensures part stability and strength in corrosive, submerged, or chemical process environments.
Processing & Manufacturing
Molding Methods: Long fiber injection molding (LFT-G), compression molding
Surface Finish: Matte to coarse textured; fiber exposure likely
Tooling Requirements: Requires abrasion resistant, high temp steel tooling due to aggressive wear from fiber content
→ High performance results require controlled molding conditions to preserve fiber integrity and realize full mechanical potential. Tool life must be managed accordingly.
Target Applications
Automotive & Mobility
Transmission housings, crossbeams, suspension brackets
→ Replaces cast metals in under hood and chassis systems requiring stiffness, heat resistance, and weight reduction.
Aerospace & Defense
Structural supports, interior mounting frames, heat shields
→ Combines lightweighting and dimensional reliability for aircraft structural components and thermal insulation zones.
Industrial & Mechanical Equipment
Pump housings, robotic arm joints, wear critical bushings
→ Maintains precision and mechanical endurance under high mechanical load, vibration, and harsh chemicals.
Electronics & Electrical Systems
Power module carriers, structural EMI shielding, high temp frames
→ Offers thermal and dimensional stability for components in power electronics, EV systems, or industrial controls.

Friction coefficient of PPS-CF
The friction coefficient of PPS (Polyphenylene Sulfide) typically ranges from 0.3 to 0.45, while PPS-CF (Carbon Fiber Reinforced Polyphenylene Sulfide) has a lower coefficient, generally between 0.2 and 0.35. The addition of carbon fiber improves hardness, wear resistance, and reduces friction, making PPS-CF more suitable for high-load, high-temperature, and high-friction applications.
