Title

Stress analysis and Strength Evaluation of Composite Scarf Adhesive Joints

Abstract

Nowadays, Composite materials usage in industrial sector as well as in Aerospace area has predominantly increased. The main reason for it has been its lightweight structure as well as high durability. The only problem which comes in its path has been tedious repair and replacement work. Many bonding techniques are used but effective strength and efficiency is not achieved. The reason for this is stress concentration over bonded area and non-uniform stress distribution. To counter this problem, scarf adhesive joining method can be brought into picture and utilized in the repairing and replacement process of composite material components and product. In our experimental study, scarf Adhesive joints tensile strength is carried out at various angles by experimentation and numerical analysis method. Araldite epoxy which is available commercially is used as adhesive and epoxy glass and Bakelite is used as Adherends. Bakelite and epoxy glass specimens are prepared at three different scarf angles with similar materials and dissimilar materials. Numerical analysis is done by a three dimensional finite element method.The stress distributions in scarf adhesive joints under static tensile loadings are analysed using three-dimensional finite-element calculations. The Finite Element Method (FEM) analysis is executed by ANSYS software. Tensile tests are carried on computerized universal testing machine. Calibrated Universal Testing machine provides breaking load values for different scarf angles specimen. Stress distribution is recorded during tensile testing to validate strength of Bakelite and epoxy glass specimens. For effective study, we have prepared 30°, 45°, and 60° scarf angle specimen for separate Bakelite, epoxy glass and then Bakelite with epoxy glass as dissimilar composite material. Experimental and FEM results are compared and found reasonable. Inference of our results shows that when the angle of scarf adhesive joint increases then the failure load values also decreases in all joints.
