The ther… Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. PEEK plastic is often used in hot water or steam environments because it maintains physical properties such as flexural and tensile strength at a high level despite the severe environment. In fact, it is very resistant to heat and wear, has a high chemical resistance, it’s sterilizable and has dielectric properties. David Kemmish "Update on the Technology and Applications of PolyArylEtherKetones" 2010. Different processing conditions are applied to fabricate flat laminates from Carbon/PEKK unitape using compression molding. Short carbon fibers dispersed within the PEEK-OPTIMA Natural matrix enhancing mechanical and physical properties for more demanding load-bearing implants and applications. When fillers are added to highly stable base polymers such as VICTREX® PEEK, the resulting composites exhibit extremely low CTE values, which makes PEEK a good candidate for applications requiring plastics with CTEs as close as possible to those of metals. The high thermal stability is provided by the diphenylene ketone groups which impart high strength and high resistance to oxidation, but make the polymer rigid. … Dynamic mechanical analysis and the morphologies of tensile fracture surfaces suggested better interfacial adhesion between the fibers and the PEEK matrix, which were in good agreement with the mechanical properties. Bone-like stiffness can reduce stress shielding by more closely matching cortical bone stiffness. Polyether ether ketone (PEEK) is part of a larger class of semi-crystalline thermoplastics called Polyaryletherketones (PAEKs).PAEKs have an assortment of useful engineering properties such as thermal stability (very important with plastics), chemical resistance, combustion resistance, high melting point, good electrical insulation, and other mechanical properties.
