Mechanical Behaviour of Carbon Steel-Aluminium Laminated Composites under Impact Tests

Composite materials are engineered by combining two or more distinct constituent materials to create a new material with properties superior to those of its individual components. These materials exhibit exceptional attributes such as high stiffness and strength, low density, excellent thermal stability, high electrical and thermal conductivity, adjustable thermal expansion coefficients, corrosion resistance, and enhanced wear resistance. In this study, Izod and Charpy impact tests were conducted on laminated composites and their parent materials, including Carbon Steel (SAE 1042) and various aluminium alloys: 6061-T6, 6082-T651, and 5083-H112. The investigation focused on comparing the mechanical properties of these composites with one another, identify the most suitable composite with superior mechanical performance. The Izod and Charpy tests were conducted, and the results indicated that the Aluminium 6082-T651 combination exhibited the highest impact resistance and superior fracture resistance among the materials tested
