Abstract:

The object of this program was to determine the effect of various hole anomalies on the static and fatigue strength of graphiteepoxy laminate and to determine the effects of installing production fasteners in graphiteepoxy laminates. Static tests at room temperature and 250 degrees F with dry and wet 1 moisture specimens indicated that only interply delaminations caused a significant strength reduction. Fastener installation tests showed blind bolts and solid rivets caused installation damage and that blind rivets, threaded rivet pins, and pull type lock bolts did not show installation damage.
