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.
1. Light and strong
Combination of CF and PP realizes low density, high specific strength and high specific modulus.
CAE analysis results
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
By locally reinforcing polypropylene with UD tape, the material’s resistance to deformation under load can be increased.
Example: Experimental results for UD tape reinforcement using a simple model of an automotive tailgate
Measurement method of displacement degree
Example: Simulation results of strain for a tailgate
3. Resistant to distortion, even at high temperatures
The material retains a high flexural modulus at temperatures approaching its melting point of 140°C.
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.
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.
Example: Sheet insertion in injection mold
Example: Tape placement molding
6. Processable into parts
The material can be processed into parts in a variety of shapes, e.g. sheets, tubes.
Example: Cross-car beam; weight reduction and short processing time
Example: automotive oil pan; molding of 3D shapes
Automotive parts
