Continuous carbon fiber CF/PEEK composite sighting frame

As a typical high-performance thermoplastic resin, PEEK has outstanding performance. When combined with continuous carbon fiber, the performance of the two materials is effectively combined, and the overall performance is even better. Due to its excellent performance, continuous carbon fiber CF/PEEK thermoplastic composite materials have been widely used in aerospace, medical, automotive and other fields, and are also the focus of research and attention of major universities, scientific research institutions, and corporate units.

As a representative of high-performance thermoplastic polymers, PEEK has a fracture toughness of up to 2.0 KJ/m, which is 20 times that of epoxy resin.

PEEK has good impact resistance, and it is one of the best impact-resistant heat-resistant resins. At the same time, PEEK has high rigidity, good dimensional stability, and a small linear expansion coefficient, and has excellent long-term creep resistance and fatigue resistance.

PEEK has excellent chemical corrosion resistance, and has strong corrosion resistance to acids, alkalis and almost all organic solvents. It is only corroded by halogens and strong acids at high temperatures, and is only soluble in concentrated sulfuric acid at room temperature.

PEEK has low moisture absorption and good moisture and heat resistance. It can still maintain good mechanical properties under high temperature and high humidity. In addition, it has outstanding hydrolysis resistance, low moisture absorption and permeability, and is resistant to steam, water and seawater.

PEEK can maintain high wear resistance and low friction coefficient at 260 ℃.

Studies have shown that short carbon fiber reinforced PEEK implanted in animals as a prosthetic material has low cytotoxicity, meets the cytotoxicity index of medical implant materials, and has good blood compatibility and tissue compatibility.

PEEK has good transmission performance and does not produce artifacts such as metal implants under X-ray and CT examinations, which is convenient for patients to be examined in medical and other aspects.
