PPS-LCF50 | 50% Long Carbon Fiber Reinforced Polyphenylene Sulfide

PPS-LCF50 is an ultra high performance, semi crystalline thermoplastic composite reinforced with 50% long carbon fiber, specifically developed for maximum stiffness, tensile strength, and dimensional stability in the most extreme mechanical, thermal, and chemical environments. This material achieves metal like structural performance with significantly lower weight, making it ideal for metal replacement in structural and high stress components.

Compared to lower fiber grades such as PPS-LCF30 and PPS-LCF40, PPS-LCF50 delivers outstanding creep resistance, fatigue performance, and load retention, even under continuous high temperature cycles and in aggressive chemical conditions. It is engineered for applications where precision, longevity, and mechanical reliability are non negotiable.

Core Performance Highlights

Mechanical Properties

Carbon Fiber Content: 50% (long chopped fibers, highly aligned during molding)

Tensile Strength: ≥ 210–220 MPa

Flexural Modulus: ~20–22 GPa

Elongation at Break: ~0.6–0.9%

Notched Izod Impact: ~35–45 J/m

→ The exceptionally high fiber content enables extreme stiffness and load bearing capability, making PPS-LCF50 a true aluminum replacement in demanding environments.

Thermal Resistance

Heat Deflection Temperature (HDT): ≥ 280 °C

Continuous Use Temperature: Up to 250 °C

→ Maintains dimensional accuracy and structural performance under prolonged thermal cycling, with minimal creep or distortion at elevated operating temperatures.

Environmental & Chemical Durability

Moisture Absorption: <0.01% — virtually zero, highly dimensionally stable

Chemical Resistance: Outstanding — fully resistant to fuels, oils, acids, bases, and aggressive solvents

→ Ensures mechanical reliability and chemical durability in harsh industrial, automotive, or submerged environments.

Processing & Manufacturing

Molding Methods: Long fiber injection molding (LFT-G), compression molding

Surface Finish: Matte to rough; high fiber visibility likely

Tooling Requirements: Requires ceramic coated or high hardness steel tooling due to severe abrasion from fiber content

→ High performance results demand precise process control to preserve long fiber integrity and achieve optimal reinforcement. Tool wear must be carefully managed.

Target Applications

Structural underbody systems, suspension arms, drivetrain carriers

→ Offers lightweight strength and dimensional stability for metal replacement in powertrain and chassis components exposed to heat, vibration, and fluids.

Aerospace & Defense

Airframe reinforcements, bulkhead panels, thermal isolation structures

→ Combines lightweighting, fatigue resistance, and thermal tolerance for mission critical aerospace components.

Industrial & Mechanical Systems

Precision pump and valve bodies, robotic arm structures, load bearing housings

→ Retains strength and geometry in mechanically demanding and chemically aggressive environments.

Electronics & Electrical Systems

Heat sink frames, structural battery mounts, high temp enclosures

→ Ideal for electrical and power systems requiring structural strength, thermal resistance, and electromagnetic shielding.
