STUDIES ON THE STRENGTH OF CARBON/EPOXY-GLASS/EPOXY HYBRID LAMINATED LAP JOINTS

The laminates of carbon fiber and glass fiber are made individually. The glass fibers used are of high strength. Two sheets of each are combined using epoxy resin mixed with hardener. The resin is spread evenly so that a good bond is made between the two sheets of fibers. The carbon fiber laminate, glass fiber laminates and glass-rubber combination laminations are made into small pieces and then made into a joint by lapping them at one their end using the adhesive. These composite single products which are made into a lap joint are tested in UTM. The strength of the composite product at the joint should be determined. The main objective of the composite joint is to improve structural stiffness and to obtain good strength to weight ratio.
