There are many uses for thin composite structures reinforced with woven fabrics, particularly with kevlar and carbon fibers, in a variety of industrial domains, particularly in the production of military jets and aircraft based on their higher specific strength. The goal of this study is to compare the tensile and flexural properties of carbon and kevlar-reinforced metal sheet laminates within the common matrix of epoxy. The study covers every step of the process, including sample preparation, testing, and analysis. Flexural and tensile strength values were analyzed for 70% volumetric ratios. This study also investigates the effect of interfacial adhesion between the metal sheet and the fiber/matrix on failure. This analysis is supported by test results and scanning electron microscopy (SEM) images. The key contributions of this study lie in enhancing understanding of the bonding mechanisms between fibers and metal sheets. Additionally, the tensile and flexural resistance of fiber laminates, specifically those reinforced with Kevlar and carbon, are comprehensively analyzed, providing valuable insights for applications in various industrial sectors.

摘要

There are many uses for thin composite structures reinforced with woven fabrics, particularly with kevlar and carbon fibers, in a variety of industrial domains, particularly in the production of military jets and aircraft based on their higher specific strength. The goal of this study is to compare the tensile and flexural properties of carbon and kevlar-reinforced metal sheet laminates within the common matrix of epoxy. The study covers every step of the process, including sample preparation, testing, and analysis. Flexural and tensile strength values were analyzed for 70% volumetric ratios. This study also investigates the effect of interfacial adhesion between the metal sheet and the fiber/matrix on failure. This analysis is supported by test results and scanning electron microscopy (SEM) images. The key contributions of this study lie in enhancing understanding of the bonding mechanisms between fibers and metal sheets. Additionally, the tensile and flexural resistance of fiber laminates, specifically those reinforced with Kevlar and carbon, are comprehensively analyzed, providing valuable insights for applications in various industrial sectors.
