Effect of Graphene Filler Content on Mechanical Strength and Hardness for Goat Hair Fibre Reinforced Epoxy Composites

Graphene when mixed in small quantity to host matrix like epoxy improves the mechanical, thermal and electrical properties. Fabrication of natural composite is made with goat hair as fibre with 37.5% fibre content by weight and graphene filled epoxy as matrix to enhance the properties. In the process of composite fabrication, five layers of goat hair fibre is sandwiched using resin by compression moulding method. Four composite specimens respectively epoxy with no Graphene content and 0.25% to 0.75% Graphene filled epoxy matrix are tested for tensile strength, flexural strength, impact strength and hardness. The mechanical properties of the four composite specimens are analysed. The experimental test results have demonstrated that graphene filled epoxy matrix reinforced with goat hair fibre specimens had better mechanical properties than composite with no graphene content.
