Composite is a material that is widely used in the manufacturing industry, especially in aircraft manufacturing. The use of composites generally lies in the airframe structure, which consists of joints. Composite joints are a method for combining structures and have become important research. The purpose of this study is to analyze the bonding strength and failure modes of single lap joint composite made of Epoxy resin and WR 600 Glass Fiber with different compositions for tensile testing. The standard for tensile testing is in accordance with ASTM D5868-01. The process started by making a specimen using the hand lay-up method with a vacuum bag. There were two types of specimens; A is a specimen with 74.82% resin and 25.18% fiber, while B is 66.42% resin and 33.57% fiber. Simply put, specimen B has less resin than specimen A. Tensile test results show that Specimen B had higher strength than specimen A. For bonding failure mode, specimen A was adhesive failure and for specimen B was cohesive failure. It was showed that the composition of the composite affects the shear lap strength. © Published under licence by IOP Publishing Ltd.
