Design, Static Analysis And Fabrication Of Composite Joints

Abstract

The Bonded joints will be having one of the important issues in the composite technology is the repairing of aging in aircraft applications. In these applications and also for joining various composite material parts together, the composite materials fastened together either using adhesives or mechanical fasteners. In this paper, we have carried out design, static analysis of 3-D models and fabrication of the composite joints (bonded, riveted and hybrid). The 3-D model of the composite structure will be fabricated by using the materials such as epoxy resin, glass fibre material and aluminium rivet for preparing the joints. The static analysis was carried out with different joint by using ANSYS software. After fabrication, parametric study was also conducted to compare the performance of the hybrid joint with varying adherent width, adhesive thickness and overlap length. Different joint and its materials tensile test result have compared.

A review of joining techniques for thermoplastic composite materials

“…He also assessed the adhesive properties of double lap adhesive joints such as elasticity and plasticity and shear strength by following the standard method ASTM D 5656. Beams et al 120 conducted static tensile and fatigue tests on bolted, adhesives, and hybrid joints and found that hybrid joints give the best performance as compared to adhesive and bolted joints. Franco et al 121 also reported that compared to simple joints hybrid joints offer higher static strength and damage tolerance.…”
