摘要: Abstract The pin bearing behaviour of woven Kevlar fibre-reinforced epoxy laminates, prepared by autoclave and oven curing methods, was examined under static dynamic loading. Static strength determined as a function bolt constraint specimen geometry with particular attention to failure modes. performance very sensitive lateral tightening: only ‘finger-tight’ nut produced ∼100% improvement in strength, compared the pin-loaded hole. Some specimens were hygrothermally conditioned indicated 10% deterioration bolt-loaded However, this well below magnitude variation which resulted different methods production. fatigue endurance limit (N ∼ 106) at 1 Hz achievable stress levels equivalent 25% maximum strength.
