TPU-LCF40 Material Overview

TPU-LCF40 (Thermoplastic Polyurethane with 40% Carbon Fiber) is an ultra-high-performance composite material that pushes the boundaries of strength and durability by combining the inherent flexibility and resilience of TPU with an even higher concentration of carbon fiber reinforcement. With 40% carbon fiber content, TPU-LCF40 offers unparalleled mechanical, thermal, and wear-resistant properties, making it ideal for the most demanding heavy-duty applications requiring exceptional strength, dimensional stability, and long-term reliability.

Mechanical Performance

The 40% carbon fiber content significantly boosts stiffness, tensile strength, and flexural strength, providing extraordinary mechanical performance suitable for high-load and high-stress applications.

• Tensile Strength: ≥ 110 MPa
• Flexural Strength: ≥ 250 MPa
• Impact Strength: ≥ 70 kJ/m²

This increased reinforcement enhances stiffness and load-bearing capacity, making TPU-LCF40 a go-to choice for structural and mechanically demanding components subjected to extreme stresses.

Thermal and Chemical Resistance

TPU-LCF40 exhibits superior thermal resistance, enabling it to maintain mechanical integrity and performance in extreme environments with elevated temperatures.

• Heat Deflection Temperature (HDT): Approx. 180°C
• Long-Term Service Temperature: Up to 150°C
• Chemical Resistance: Outstanding resistance to oils, solvents, and aggressive chemicals like acids and alkalis, making it suitable for harsh industrial environments.

Wear Resistance and Processing Characteristics

With its high carbon fiber content, TPU-LCF40 provides remarkable wear and abrasion resistance, ideal for parts exposed to constant friction, repetitive motion, or harsh operational conditions.

• Wear Resistance: Excellent performance under high-friction or abrasive conditions.
• Processing Methods: Compatible with injection molding, extrusion, and 3D printing, though higher processing temperatures and optimized settings are required due to the increased viscosity from the high fiber load.

Note: While TPU-LCF40 offers enhanced stiffness, the increased carbon fiber content slightly reduces flexibility compared to TPU-LCF30.

Environmental Adaptability

TPU-LCF40 maintains low water absorption and superior dimensional stability, ensuring consistent performance in humid or outdoor environments. Its high carbon fiber content makes it particularly suited for applications requiring both structural rigidity and environmental resilience.

Applications

Thanks to its unmatched strength, wear resistance, and thermal stability, TPU-LCF40 excels in a variety of advanced applications:

• Automotive Industry: Heavy-duty brackets, under-hood components, engine mounts, and structural reinforcements.
• Consumer Electronics: Reinforced casings, durable housings, and robust structural components for electronic devices.
• Industrial Manufacturing: High-load gears, abrasion-resistant seals, bushings, and heavy-duty machine components.
• Sports and Recreational Equipment: High-strength frames, reinforced grips, and components for extreme performance use.
• Aerospace and Defense: Lightweight yet robust components requiring exceptional strength and thermal resistance.
