TAFNEX™ CF/PP is an unidirectional tape (UD tape) composed of carbon fiber and polypropylene (PP) achieved by unique technology of Mitsui Chemicals.
Using this material for local reinforcement can reduce part weight while retaining strength.
Since it is a thermoplastic composite, it offers excellent processability; short processing time, secondary processing, and so forth.
In the automotive and bicycle field, TAFNEX™ CF/PP can contribute to reduce part weight, improve impact resistance and control vibration.

2. Reinforcement effect to increase mechanical properties of PP

Significant increase of improvement in resistance to stress in standard specimens was observed by the reinforcement of CF/PP UD tape.
- Flexural modules: 10 times
- Impact resistance (Izod): more than 10 times

3. Resistant to distortion, even at high temperatures

The material retains a high flexural modulus at temperatures approaching its melting point of 140°C.

Resistant to distortion, even at high temperatures

4. Remain mechanical properties in immersed and high-humidity environments

Since the material does not absorb water, bending strength can be maintained even when immerged in water for an extended period of time.

Experimental method: Based on ASTM D790

5. High processability

Since TAFNEX™ CF/PP is a thermoplastic composite, it offers excellent processability.
Shorter cycle time than thermoset composite is achieved due to the absence of heat-curing process.
In addition, molded parts can be reprocessed under heat or pressure.
