PEEK-LCF30 Material Overview
PEEK-LCF30 is a high performance thermoplastic reinforced with 30% long carbon fiber, engineered for demanding applications that require exceptional mechanical strength, dimensional stability, and chemical resistance. The increased carbon fiber content significantly boosts stiffness, wear resistance, and mechanical strength, while retaining the remarkable thermal and chemical properties of pure PEEK.
Mechanical Properties
PEEK-LCF30 offers superior mechanical performance compared to PEEK-LCF20, making it suitable for applications that require even higher strength and wear resistance, especially under extreme conditions.
Tensile Strength: ≥ 280 MPa
Flexural Strength: ≥ 500 MPa
Impact Strength: ≥ 3.5 kJ/m²
With 30% long carbon fiber reinforcement, PEEK LCF30 provides enhanced stiffness, fatigue resistance, and dimensional stability compared to lower carbon fiber PEEK variants, making it ideal for high stress applications.
Thermal and Chemical Resistance
PEEK-LCF30 retains the excellent thermal and chemical resistance properties of pure PEEK. The addition of carbon fiber has a minimal effect on these properties, ensuring outstanding performance in extreme environments.
Heat Deflection Temperature (HDT): Approx. 350°C
Long-Term Service Temperature: Up to 270°C
Chemical Resistance: Excellent against oils, fuels, solvents, and aggressive chemicals
PEEK LCF30 is particularly well suited for industrial and automotive applications where both high thermal stability and resistance to harsh chemicals are required.
Wear Resistance and Processing
The increased carbon fiber content (30%) significantly improves wear resistance, making PEEK LCF30 ideal for applications exposed to higher friction and stress. The material retains reasonable processability while offering exceptional durability and wear resistance.
Wear Resistance: Excellent under high friction and stress
Processing Methods: Suitable for injection molding and extrusion at temperatures similar to or slightly higher than those for PEEK LCF20
PEEK-LCF30 is a durable material ideal for high performance applications requiring enhanced wear resistance and reliability.
Environmental Adaptability
PEEK-LCF30 exhibits low moisture absorption and superior dimensional stability, ensuring reliable performance in fluctuating temperature and humidity conditions.
Water Absorption: Low
Dimensional Stability: Excellent, even under varying temperature and humidity environments
Applications
PEEK-LCF30 is suitable for a wide range of demanding applications requiring high mechanical strength, thermal stability, and superior wear resistance, including:
Automotive: Structural components exposed to high mechanical loads, extreme temperatures, and aggressive chemical environments.
Industrial Manufacturing: High performance components like gears, bearings, bushings, and seals under heavy wear and stress.
Aerospace: Lightweight, high strength components for aircraft and spacecraft, requiring high temperature resistance and dimensional stability.
Electronics: Durable housings, connectors, and enclosures exposed to high mechanical stresses.
Medical Devices: Biocompatible components that demand exceptional durability and resistance to sterilization processes.
