Abstract

In many different fields, including tensile strength, reduced thermal expansion, and an amazing strength-to-weight ratio, fiber-reinforced polymer composites are gradually replacing conventional materials. This work mostly addresses the development and evaluation of the mechanical characteristics of epoxy composites improved with glass fibers and sisal. Among the benefits are biodegradability, lower weight, and more specific strength. Sisal polymer composites are included under natural fiber composites. Including sisal strands into glass fiber-reinforced polymers (GFRPs) strengthens them and provides a substitute for more traditional GFRPs. The possible improvement of mechanical characteristics in epoxy composites by means of glass fibers and sisal is investigated in this work. This work will discuss applications related to tensile characteristics, impact resistance, and flexural strength in the building and automotive domains. We fabricated the sisal-glass epoxy composites containing fibers using the hand lay-up technique. Layers of sisal fiber made up the inside; layers of glass fiber made up the outside. Testing the composite specimens’ tensile strength, flexural strength, and impact resistance made it much easier to figure out their mechanical properties. When sisal fibers were added, the tensile strength went down compared to glass fiber-reinforced polymers (GFRPs), even though the flexural strength and impact resistance went up. While the maximum flexural stress attained over 200 N, the sisal-GFRP composites displayed an impact strength of 375.29 J/m. The results show that epoxy composites strengthened with glass fibers and sisal do a better job of resisting impacts and being strong when bent. This makes them a better material to use instead. Combining synthetic and natural fibers with composites can help you to achieve this. Future developments improving tensile performance could benefit more general uses.

Keywords: Glass fibre reinforced epoxy, Sisal fiber, Composite materials, Tensile strength, Flexural strength, Filler material, Interfacial bonding
