Abstract
Fibre-reinforced polymer composites have found extensive applications in the oil, gas industries. The use of interlayer Hybrid composite pipes are used in several engineering applications is increasing due to their superior properties such as high specific strength, high chemical resistance and resistance to UV rays .Hybrid composite adherends lap joints need to be explored to develop a cost-effective combination of materials to address the certain complex behavior due to hybridization . It is essential to understand the mechanical behavior of Hybrid Tubular Lap Joints (HTLJ) to provide design guidelines for safe performance of joint. In the present work Failure analysis of the adhesively bonded HTLJ is performed. Stress distributions within the joint region are estimated under tensile load. Failure indices at critical interfaces are evaluated by using Quadratic Failure Criterion (QFC).The failure index values of HTLJ were obtained for different overlap lengths. Effective overlap length for suitable performance of the joint is determined based on the Tsai-Wu failure criterion.
