Continuous carbon fiber reinforced CF/PEEK Unidirectional Prepreg will not only bond better at the bone interface than other materials artificial joints but continue to promote protein synthesis of bone cells. Thermoplastic CF/PEEK Unidirectional Tape are environmentally friendly, recyclable, hot melt process, can be processed into other amorphous shapes of products, resin formula adjustable space to meet the requirements of different special performance processes.
The aerospace applications of continuous carbon fiber reinforced PEEK Unidirectional Tape with high strength, lightweight, excellent fatigue resistance, dimensional stability, wave-transparent, shock and vibration damping, and friction characteristics (improving fuel utilization, improving safety and reliability) include fuselage belly panels, tail fins, front landing gear doors, around the engine, fuselage skin and other components.
Particularly suited for the developing direction of the automotive industry are PEEK UD Prepreg. Our products comprise a seat & its skeleton, window guides, door panel, bumper bracket, hoods, front-end bracket, pedals, instrument panel skeleton, deflector, cabin floor, spare tire box, battery tray & automotive intake manifold; PEEK engine floor guard, PEEK entertainment module carrier, PEEK bracket, PEEK airbag enclosure, etc.
The Unidirectional PEEK Compositel has good fatigue resistance, defects organization of crack expansion, the resin can resist surface chemical attack, so as to effectively prevent seawater erosion, is lower than the biological epiphytes, and can extend the overall service life of the ship.
With blade size beyond 40m and the power of wind turbine beyond 3MW, the performance of traditional glass fiber composite has approached its limit, and PEEK Reinforced Prepreg are needed for blade fabrication.
