摘要: Fibre/matrix adhesion and fibre length have a significant effect on the impact behaviour residual resistance of thermoplastic composites. A comparison between virgin materials impacted at different speeds is given in terms results from tensile loading/unloading tests. parameter proposed which rate transmitted to quantified maximum load applied during impact. The damage generated evaluated through measurements elastic moduli Poisson's ratio use acoustic emission microscopic observations has been necessary identify sources damage.
