Strength improving of damaged composite plate by repairing

Utilization rate of adhesive substances and pin joints are gradually improved on machine and structure components. Especially, the importance of joints wit adhesives and pin joints is grown more and more in aviation, aerospace industry, automotive, infrastructure systems, medicine, electronic packing, sport, building and marine industries that might have reliability for long working periods. One of the major way of energy disposal of contemporary systems is performing the disposal of fuel by decreasing weight of system. Practicable different materials joint, obtaining regular tensile strength distribution and more smooth surfaces were made adhesives more effective. In this study, it is investigated that which joining method in composite plates is useful and strength.Experimental study was performed in four different ways. These ways are glue with overlapping, glue with foreheads, pinning with overlapping and foreheads. The adhesive joints are divided in two groups; One of these is fibrous the other nonfibrous joints.
