Abstract

Composite materials like Carbon Fiber Reinforced Plastics (CFRP) and Glass Fiber Reinforced Plastics (GFRP) are increasingly used in aircraft structure due to high specific strength and specific stiffness. In this work, CFRP and GFRP laminates have been fabricated using hand layup and vacuum bagging techniques, then the fabricated CFRP and GFRP laminates are cut into the required dimensions and are used as dissimilar composite adherends to construct the composite lap joints. The designed mould is used to fabricate the single and dual adhesive bonded lap joint specimens using AV138 brittle and Araldite-2015 ductile adhesives between dissimilar composite adherends (CFRP and GFRP) according to ASTM D 5868 standard. X-ray radiography testing has been carried out to assess the quality of the specimen. Uniaxial tensile tests have been conducted to obtain the single and dual adhesive bond strength. From the study, it is found that the use of dual adhesives helps in increasing the bond strength between the dissimilar composite adherends.
