Abstract
The dependence of material properties and residual stress formation on the crystallinity of thermoplastic composites necessitates detailed analyses regarding the melting behaviour and the crystallisation kinetics of employed semi-crystalline matrices as well as accurate crystallisation models. This paper investigates a novel low-melting poly(aryl ether ketone) (LM-PAEK) reinforced with carbon fibres, in the form of TC1225 unidirectional tape, based on isothermal and non-isothermal differential scanning calorimetry (DSC). It is shown that the LM-PAEK matrix features a double melting behaviour and exhibits an absolute crystallinity of roughly 18%. Kinetics parameters are derived from the DSC analyses and the applicability of selected crystallisation models for predicting the relative crystallinity is evaluated based on a comparison with the DSC data. Under isothermal conditions, the modified Hillier model and the parallel Velisaris–Seferis model yield good agreement. In contrast, a dual Nakamura model and a dual Kamal–Chu model yield merely moderate agreement under non-isothermal conditions.
