Continuous carbon fiber CF/PEEK composite plate
CF/PEEK thermoplastic carbon fiber composite materialsare generally based on satin weaving, with large gaps between satin patterns, and staggered gaps are more conducive to the impregnation or wetting of PEEK rubber. PEEK material has poor fluidity and fast cooling and curing speed. Therefore, the difficulty of wetting carbon fiber composite materials is much higher than that of epoxy carbon fiber composite materials. Compared with ordinary epoxy carbon fiber composite materials, PEEK carbon fiber composite materials have superior performance and solve many problems existing in epoxy composite materials. At present, they are widely used in medical treatment.
Advantages
1. High strength. Some mechanical properties of composite materials have exceeded those of ordinary metals, such as aluminum alloy.
2. Light weight. Compared with aluminum alloy, it is only 1/2 of its weight, and compared with stainless steel, it is only 1/5 of its weight.
3. Transparent to X-rays, it can maintain good light transmittance.
4. The processing size is stable. The material has good stability and will not deform after processing.
5. High temperature resistance. It can be used for a long time at 260℃. After compounding, it can withstand repeated deformation.
6. Corrosion resistance. After compounding, PEEK forms another layer of coating on carbon fiber, making the corrosion resistance of the composite material more outstanding.
7. Good interlayer bonding strength. Since PEEK has anti-creep force, PEEK polymer can withstand relatively large pressure for a long time, will not expand over time, and has good fiber-matrix interface bonding strength.
8. Impact resistance. Thermoplastic resins are usually linear molecular chains because of their good toughness and high impact energy resistance.
9. Recyclable. Thermoplastic carbon fiber composites have the characteristic advantage of being directly recyclable.
10. Foreign scientific experiments have shown that implantable carbon fiber reinforced polyetheretherketone composites are not only non-cytotoxic, but also can promote protein synthesis and osteogenesis of bone cells. When used as artificial joint prostheses, they show good osteoblast proliferation and adhesion capabilities.
