Abstract: Adhesive bonded joints with laminated FRP composites play a significant role in many structural applications especially in space, aircraft and automobile industries. However, designing the composite bonded joints is quite complex, because their performance is limited by the characteristics of the composite laminate adherends and bi-material interface which usually have low interlaminar strengths. The project aims at detail Analytical, FEM analysis and experimental analysis of adhesive joint. The following are the main objectives of the project. Adhesive joints are expected to retain a significant proportion of their load bearing capacity for the entire duration of the service life of the bonded structure..The single-lap shear test is the most widely used method for producing in shear strength data on adhesively bonded joints. The E-glass plate manufactured consist of combination of different mats prepared by mixing of proportionate combination of cobalt resin & hardener which have more strength than adhesive material AV-119 of varying thickness. The E-glass material plates of varying thickness where joined by lap join of varying thickness formed using material AV-119Variations of this test method are included in both national and international standards . The single-lap specimen is easy to prepare and test. Special care is needed to ensure that bond line thickness is uniform. Adherend surfaces should be prepared according to ISO 4588 for metals and ISO 2818 for polymer matrix composites (PMCs). Testing is conducted using standard tension/compression mechanical test equipment with a suitable pair of self-aligning to hold the specimen.
