In recent years, continuous CF/PEEK composite materials have frequently appeared in medical device exhibitions and have also begun to emerge in medical device companies. What are the unique advantages of this composite material that attracts so much attention in the medical device industry

1What is CF/PEEK 

Continuous CF/PEEK composite material refers to a composite material that uses continuous carbon fiber CF as reinforcement and PEEK, the first special engineering plastic, as the matrix. The two are formed through a high-temperature and high-pressure molding process, and the resin material is impregnated into the carbon fiber, and the two are organically combined to form a composite material.

Compared with traditional aluminum alloy and stainless steel materials, the density of aluminum alloy is 2.8g/cm ³ , the density of stainless steel is 7.3g/cm ³ , and the density of continuous CF/PEEK composite material is 1.5-1.6g/cm ³ , which is light in weight but high in strength. The test results show that some performances of CF-PEEK have exceeded those of stainless steel. At the same time, continuous carbon fiber reinforced PEEK has good X-ray transmittance, making clinical surgery more intuitive and safe. Carbon fiber reinforced materials do not feel cold like metal, and doctors feel more comfortable when operating.

Compared with traditional carbon fiber powder modified PEEKCF30 material, the high strength and high modulus characteristics of CF-PEEK give the composite material very high strength, modulus and deformation resistance. The mechanical strength is increased by at least 3 times, and the modulus is also increased by at least 3 times, giving it better dimensional stability and deformation resistance.
