Development and Characterization of Epoxy-Based Laminated Composites: Experimental Characterization and Numerical Simulation

Abstract

The objective of this project is twofold. First, it focuses on the development of a new hybrid composite material intended for use in various industrial sectors, with particular emphasis on the aeronautical field. This composite is composed of plain weave woven carbon fiber, 8-harness satin (8HS) glass fabric, and metallic reinforcement made of galvanized steel, all embedded in an epoxy resin matrix. The combination of these materials aims to achieve enhanced mechanical performance and durability under different loading conditions. Second, the project involves a comprehensive characterization of the developed composite. This includes experimental mechanical testing, specifically tensile tests and three-point bending tests, in order to determine key properties such as Young's modulus and ultimate tensile strength. In addition to the mechanical tests, micrographic and macrographic analyses are conducted to investigate the internal structure and failure mechanisms of the composite material. These analyses provide insight into how different types of damage initiate and propagate under mechanical loading. To complement the experimental work, a numerical simulation was carried out using ABAQUS finite element software. The Young's modulus of the carbon fiber-based laminated composite was estimated numerically and then compared with the experimental results. The comparison shows a satisfactory agreement, validating the accuracy and reliability of the simulation approach used in this study.
