Morphological characterization of polyetheretherketone–carbon fiber composites

摘要

AbstractThe effect of processing conditions on the morphology of polyetheretherketone (PEEK) graphite reinforced composites (APC‐2) has been characaterized. Differential scanning calorimetry was utilized to examine the effect of quench rate on recrystallization where a change in mechanism was observed at a rate of 5°C/min. Optical microscopy revealed a decrease in spherulite size and a reduced degree of transcrystallinity at the graphic fiber surface with increasing quench rates. Dynamic mechanical analysis indicated a change in relaxational processes in theTgregion with varying quench rat
