摘要: Abstract The toughness behaviour of some blends and a PA/CF composite under dynamical loading (1 m/s) based on the J -integral was studied. Different methods were used for tests. It can be shown that multiple specimen stop-block technique gives most conservative results. Furthermore influence thickness crack resistance instrumented Charpy impact test enables determination valid curves plastics with small geometries. advantages disadvantages using known standards metallic materials in comparison to ESIS TC4 testing protocol discussed physical concept is compared empirical description R-curve .
