TPU-LCF30 Material Overview
TPU-LCF30 (Thermoplastic Polyurethane with 30% Carbon Fiber) is an ultra-high-performance composite material that combines the flexibility and resilience of TPU with the superior strength, stiffness, and wear resistance provided by 30% carbon fiber reinforcement. This composition significantly enhances mechanical, thermal, and wear-resistant properties, making it ideal for heavy-duty applications that demand high strength, durability, and moderate flexibility.
Mechanical Performance
With 30% carbon fiber, TPU-LCF30 offers outstanding mechanical properties, making it suitable for high-stress applications requiring exceptional strength and wear resistance.
- Tensile Strength: ≥ 90 MPa
- Flexural Strength: ≥ 200 MPa
- Impact Strength: ≥ 60 kJ/m²
The increased carbon fiber content maximizes stiffness and durability, making TPU-LCF30 an ideal choice for load-bearing components and parts subjected to high mechanical stress.
Thermal and Chemical Resistance
The enhanced carbon fiber reinforcement improves TPU-LCF30’s thermal performance, allowing it to operate in more challenging environments with higher temperatures.
- Heat Deflection Temperature (HDT): Approx. 160°C
- Long-Term Service Temperature: Up to 130°C
- Chemical Resistance: Excellent resistance to oils, solvents, and mild acids, suitable for harsh industrial environments.
Wear Resistance and Processing Characteristics
TPU-LCF30 exhibits superior wear and abrasion resistance, making it ideal for components that experience constant friction or high wear. However, the higher carbon fiber content reduces flexibility slightly and may require optimized processing conditions.
- Wear Resistance: Very high resistance under high-friction conditions.
- Processing Methods: Compatible with injection molding, extrusion, and 3D printing, though processing adjustments (e.g., higher temperature and pressure) are necessary due to increased fiber content.
Environmental Adaptability
TPU-LCF30 retains its low water absorption and excellent dimensional stability, even in humid or outdoor conditions, ensuring reliable performance in demanding industrial and environmental applications.
Applications
Thanks to its enhanced mechanical, thermal, and wear-resistant properties, TPU-LCF30 is suitable for a wide range of demanding applications, including:
- Automotive Industry: Heavy-duty brackets, structural reinforcements, engine covers, and high-load components.
- Consumer Electronics: Robust housings, protective casings, and load-bearing structural parts.
- Industrial Manufacturing: High-durability gears, bearings, seals, and connectors.
- Sports Equipment: Durable frames, high-strength grips, and performance-critical components.

Friction coefficient of TPU-LCF
The friction coefficient of TPU is typically between 0.3 and 0.5, while TPU-CF, with added carbon fiber, lowers the friction coefficient to between 0.2 and 0.4. The smaller the value, the better the wear resistance. Therefore, TPU-LCF generally offers better wear resistance than pure TPU, especially under high-load conditions.
