Peek specific heat capacity
WebWe measured specific heat capacity of PEEK/AgNP composites from the five last of 20 min isotherms at 17 "C, 32 "C and 47 "C. … PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. The processing conditions used to mould PEEK can influence the crystallinity and hence the mechanical properties. Its Young's modulus is 3.6 GPa and its tensile strength is 90 to 100 MPa. PEEK has a glass transition temperature of around 143 °C (289 °F) and melts around 343 °C (662 °F). Some grades have a useful operating temperatur…
