The strain-rate and temperature dependence of the mechanical properties of polyetherketone and polyetheretherketone

ABSTRACT The mechanical properties of polyetheretherketone and polyetherketone were studied as a function of strain rate and temperature in the ranges 10⁻3 to 103s⁻1 and 20–200°C. At temperatures below the glass transition temperature, Tg, the strain-rate sensitivity of both polymers was found to be...
