Abstract
In order to evaluate the influence of heat developed during the composites machining process, the effect of heat during short ageing periods on the properties of carbon fibre reinforced polymer (CFRP) composites was investigated in this study. Impact energy absorption (Charpy) and tensile strength tests were carried out on the composite after exposing it to different ageing temperatures during 60, 120 and 180 second intervals. The overall properties of the composite were little affected. The variation of the ageing time showed to have no influence, whereas the viscoelastic properties showed an increase with the ageing temperature increasing up to Tg due to a post curing effect, and a further decrease at higher ageing temperatures due to a subsequent damage in the matrix.
