Static Strength of Film Reinforced Multi-Fastened Mechanical Joints in Fibrous Composites
The joint strengthening effects of transversely-isotropic boron film reinforcement added to fibrous laminates has been demonstrated for single fastened joints in earlier experimental work. It was the configurations where multiple fasteners, rather than single bolts, transferred the load. Bidirectional (plus or minus 45 deg) graphite fiber/epoxy resin composites were fabricated to form a series of double lap bolted joint models, each containing three bolts at constant pitch distance. The specimens were tested to measure the joint strengthening effectiveness of colaminated boron/polymide film, introduced locally at 6 or 12 volume percent levels. The results were that such film additions increased the load transfer capacity of the joint systems nearly double that of the corresponding fiber-only specimens. (Modified author abstract)
