Enhanced Mechanical Properties of Epoxy-Based Composites Reinforcedwith E-Glass and Aramid Fibers

This study investigates the mechanical properties of epoxy-based composites reinforced with glassand aramid fibers. The composites were fabricated using۱۰۰ and ۱۰۰۰𝑔𝑟/𝑚۲ plain E-glass and ۱۰۰۰𝑔𝑟/𝑚۲aramid fibers, combined with epoxy resin and triethylenetetramine (TETA) as curing agent. Tensilestrength and metal-steel adhesion properties were examined through tensile strength tests and pullofftests for each sample. The results indicated that composites reinforced with aramid fibersexhibited significantly higher tensile strength compared to those reinforced with E-glass fibers.Furthermore, the ۱۰۰𝑔𝑟/𝑚۲ plain E-glass composites demonstrated superior steel adhesion propertiescompared to aramid fiber composites and provided better tensile strength than the ۱۰۰۰𝑔𝑟/𝑚۲E-glassfiber composites. These findings suggest that incorporating aramid fibers and optimizing fiber weightcan significantly enhance the mechanical performance of epoxy-based composites, making themsuitable for advanced structural applications requiring high strength and adhesion.
