Evaluation of Ultimate Strength and Fundamental Frequency of Fiber/Epoxy and Fiber/Al6061 Composite Plate

Abstract

Polymers and metal composites have emerged as a significant class of materials for cutting-edge engineering applications in the current material research and development environment because of their low cost, ease of design and manufacturing, and excellent and enhanced mechanical performances. The motto behind the present work is to develop a class of such materials and to study the mechanical properties of epoxy-based Glass (G/E), Graphite (Gr/E), Aramid (A/E), Carbon HM Types (C/E), and Multi-Walled Carbon Nanotube Composites (MWCNT/E) and aluminum-based MWCNT composites. An analytical solution and finite element analysis are used to evaluate and obtain the optimum mechanical properties of the lamina of the composites, such as ultimate longitudinal tensile strength, transverse tensile strength, shear strength, and the fundamental frequency of the composite plate analysis. All-side fixed boundary conditions have been used in the present study. In addition to the above, a detailed demonstrative analysis based on the after-effects of the modulus ratio and the volume fraction of the fiber on the ultimate tensile strength has also been made. In addition, the CNT AMC plate has been examined, with the findings being compared to the composite plate of Epoxy Metal Matrices (EMCs).
