Development of A Multi-Stage MATLAB Algorithmic Quantification Using Computational Processing of Stress-Strain Data in Carbon/Glass Epoxy Composites

Abstract

Composite materials have long been in great demand for industrial purposes, particularly in the field of lightweight automobile and aircraft applications. The theory of numerical analysis provides a useful account of how Fibre-reinforced composites can be developed to prevent failure analyses and produce new composite materials. Therefore, to get an advantage from this theory, an effort has been made in this research. A systematic, Multi-stage algorithm based on MATLAB software was established to generate a code that can manipulate data of tensile and flexural tests for composite materials made from glass fibre epoxy composites (GF/Ep) and carbon fibre epoxy composites (CF/Ep). The current numerical framework was implemented using suggested code to handle data from stress-strain curves and predict ultimate strength, strain, and fracture toughness values, undergoing a validation process. The key findings were the GF/Ep-based composite showed better strain failure and an energy absorption value of 12.3 MJ/m³/and 7.0 MJ/m³ in tension and flexure, respectively. This is suggested to have better performance in fracture toughness.  Furthermore, the outcome results also showed that on GF/Ep, it is less stiff, with a value of 21.3 GPa and a bending failure value of 400 MPa.
