Abstract

Kevlar is a synthetic fiber that has become well-known all over the globe because of its many industrial uses. It functions well as a composite material and is mostly used in conjunction with other materials. This study discusses the fabrication of epoxy composites with different proportions of Al₂O₃ and SiC nanoparticles with Kevlar fiber. In this process, SiC, and Al₂O₃ nanoparticles were added to Kevlar fiber and fabricated the composite by a compressed moulding machine for shear, tensile and impact tests. From these test results, incorporating Al₂O₃ and SiC nanoparticles with Kevlar fiber under various compositions (1% to 4%) influences the composite mechanical behaviour such as strength. KBS 2 has the highest tensile strength of the four sample composites, measuring 5628 N/cm², among the Kevlar fiber reinforced polymer composites containing epoxy resin. This is the highest value among the composite samples. Additionally, it is worth seeing that the shear strength of the Kevlar fiber-reinforced polymer composite featuring the KAS 2 value of 7735 N/cm² has the highest value from the other composite including the KAS 1, KAS 3 and KAS 4. Moreover, the Kevlar fiber-reinforced polymer composite with KAS 2 (4.76 J) exhibits a larger impact strength than the composite with KAS 3 (3.42 J), KAS 1 (4.26 J, and KAS 4 (4.54 J). The findings indicate that Kevlar fiber reinforced with 3% Al₂O₃ and 2% SiC nanoparticles (KAS 2) exhibits superior strength and rigidity compared to the other nanoparticle combinations utilised in Kevlar fiber composites.
