Introduction to TPU-CF20 Material

TPU-CF20 (Thermoplastic Polyurethane with 20% Carbon Fiber) is a high-performance thermoplastic elastomeric composite that integrates 20% carbon fiber reinforcement within a TPU (thermoplastic polyurethane) matrix. The increased carbon fiber content provides significant enhancements to the mechanical properties of the material, offering greater strength, stiffness, and durability while still maintaining the flexibility inherent to TPU. TPU-CF20 is ideal for demanding applications where a balance of elasticity, wear resistance, and superior mechanical performance is required. It serves various industries, including automotive, industrial manufacturing, and consumer products.

Characteristics and Values for Enhanced Performance

Carbon Fiber Content: 20%
The 20% carbon fiber reinforcement in TPU-CF20 significantly improves its tensile and flexural strength, enabling the material to handle even higher mechanical loads while still maintaining adequate flexibility for a wide range of applications.

Tensile Strength: ≥ 100 MPa
TPU-CF20 offers superior tensile strength, with the capacity to withstand higher mechanical stress without permanent deformation. This makes it ideal for demanding applications requiring both strength and flexibility.

Flexural Strength: ≥ 150 MPa
The material exhibits outstanding flexural strength, enabling it to resist bending forces and recover its shape even after repeated flexing. This ensures long-term durability in applications subject to frequent flexural stress.

Impact Strength: ≥ 50 kJ/m²
With excellent impact resistance, TPU-CF20 can absorb shock loads effectively, making it suitable for applications exposed to sudden mechanical stresses or impacts.

Thermal Properties

Heat Deflection Temperature: Approximately 150°C
TPU-CF20 remains stable at higher temperatures, providing reliable performance in environments up to 150°C.

Long-Term Service Temperature: Up to 120°C
This material maintains its mechanical properties and dimensional stability under moderate to high-temperature conditions, making it ideal for long-term use in demanding thermal environments.

Chemical Stability

TPU-CF20 offers good chemical resistance, particularly to oils, fuels, and solvents, although its chemical resistance is not as high as some specialized composites. Its low moisture absorption further ensures reliable performance even in humid or wet conditions.

Processing Characteristics

TPU-CF20 is compatible with standard processing techniques such as injection molding, extrusion, and 3D printing. The increased carbon fiber content improves mechanical properties without substantially complicating the processing, enabling the production of high-precision, durable components.

Other Characteristics

Low Water Absorption: TPU-CF20 maintains its dimensional stability even when exposed to moisture, making it ideal for use in humid environments.

Superior Wear Resistance: The higher carbon fiber content enhances wear resistance, making TPU-CF20 perfect for components subjected to friction or repetitive motion, such as seals, gaskets, bushings, and protective covers.

Applications

Automotive Industry: TPU-CF20 is excellent for high-performance components like gaskets, seals, bushings, and shock-resistant parts, where both flexibility and strength are essential.

Industrial Manufacturing: Ideal for heavy-duty components such as protective covers, conveyor belts, and flexible tubing, where high wear resistance and mechanical durability are necessary.

Consumer Goods: TPU-CF20 is used in premium products like footwear, mobile cases, and sporting equipment that require exceptional durability and flexibility.

Friction coefficient of TPU-CF

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-CF generally offers better wear resistance than pure TPU, especially under high-load conditions.

What are CF Reinforced Thermoplastic Composites?

CF Reinforced Thermoplastic Composites are materials where carbon fibers are incorporated into a thermoplastic matrix. They combine the strength and stiffness of carbon fibers with the processability and recyclability of thermoplastics. For instance, they are used in automotive parts like bumper beams.
What are the benefits of CF Reinforced Thermoplastic Composites over traditional composites?

The key benefits include faster production cycles, easier recyclability, and better impact resistance. They also offer design flexibility. An example is in the manufacturing of consumer electronics casings where complex shapes can be achieved more easily.
How are CF Reinforced Thermoplastic Composites processed?

Common processing methods include injection molding, extrusion, and compression molding. Injection molding is widely used for mass production. For example, in the production of small components for the medical industry.
What industries use CF Reinforced Thermoplastic Composites?

They are utilized in aerospace, automotive, medical, and sports equipment industries. In aerospace, they can be found in interior components. In the medical field, they might be used in prosthetics.
How does the carbon fiber content affect the properties of the composites?

Higher carbon fiber content generally leads to increased strength and stiffness but may reduce ductility. A moderate content is often balanced for specific applications. For example, a higher content might be preferred in structural parts of a race car.
What are the challenges in using CF Reinforced Thermoplastic Composites?

Challenges include higher material costs, complex processing equipment requirements, and ensuring uniform fiber dispersion. Issues with adhesion between the fibers and the matrix can also arise. An example is in achieving consistent quality in large-scale production.
