Fracture behaviour of aged polymers
Keywords:Ageing, Dynamic fracture, Composite, Instrumented Charpy,
The dynamic fracture behaviour of three types of composite materials was studied. Two of the composites were manufactured from the same thermoplastic resin, reinforced with glass or carbon fibre fabric, respectively; the other one, was manufactured with an epoxy resin, reinforced with carbon fibre fabric. The composites were subjected to accelerated ageing effect on a climatic test chamber, under humidity and temperature control, for different notch-Width ratios. The dynamic fracture behaviour was analysed by applying the ASTM E 24.03.03 Standard proposal to Charpy instrumented test results with the goal of validating this testing procedure for composite materials.
