Abaqus Simulation on Basalt Fibre Reinforced Polymer Epoxy Tube Subjected to Axial Compression for Energy Absorption

Abstract

Abstract In practical application, fibre reinforced polymer (FRP) technology is implemented as the outer jackets in structural elements such as column, beam and in automobile engineering as light weight components in the head liners of car, brake pads and energy. In civil engineering FRP is mainly used in the retrofitting technique against corrosion, in columns, piles and poles. The research aims to provide a recyclable, natural, low-cost energy absorption material capable of increasing the load bearing capacity of the structure by increasing the fabric layer. The study focuses on the finite element analysis (FEM) of the energy absorption characteristics of basalt fibre reinforced polymer epoxy tube (BFRPE) subjected to axial compression with varying BFRPE layers. The results also discuss the failure modes of the specimens using abaqus. Parameters such as the energy absorption, crush force efficiency (CFE) are discussed. Energy absorption is defined as the area under the load displacement and CFE is defined as the ratio of the mean load to that of the initial peak force. The test results indicate that as the number of layers increases the ultimate load and CFE of the tube also increases. Compared to flax fibre reinforced polymer the thickness of the basalt fibre is very less with better energy absorption.
