Abstract:
The paper outlines the current status of mechanical testing, identification of
failure mechanisms and data analysis related to delamination cracking in high
performance laminates made via the prepreg/autoclave route, strengthened in the
through-thickness direction by Z-pinning. The applied loading cases under
consideration are limited to Mode I and Mode II. Sample preparation, test
methodologies and applicability of data reduction schemes are considered, with
data obtained from within the range of aerospace and Formula 1 grades of carbon
fibre / epoxy composites. Micromechanisms of failure in the three dimensional
tests specimens are shown to be dependent on the architecture of the fibre
reinforcement (i.e. unidirectional versus woven fabric prepregs), particularly
in the case of Mode II loading.
