摘要: Abstract Pin bearing behaviour of a range laminate systems comprising unidirectional and woven carbon fibre-reinforced ordinary toughened epoxy matrices were examined under static dynamic loading. Static properties determined various levels bolt constraint with particular attention to onset failure modes. Load-amplitude controlled fatigue tests conducted at 3 Hz, approximately 40% hole deformation which corresponds the strains experienced maximum loads. Some test-pieces hygrothermally conditioned 56°C 95% relative humidity. The depended mainly on type, ply stacking sequence specimen geometry. definition strength as in ASTM D953-87 was found have no material integrity. However, initiation loading greater significance, particularly relation behaviour.
