Abstract: Hybrid polymer composite materials have greater flexibility to control the required properties to a considerable extent by the choice of matrix. The properties are tailored in the material by selecting different kinds of fibre incorporated in the same resin matrix. This work concerns the production of glass-basalt hybrid fibre reinforced composite with and without Zirconia(ZrO₂) fillers. All the composites were fabricated by the hand layup technique followed by compression moulding. The mechanical properties such as tensile strength, tensile modulus, flexural strength, flexural modulus and hardness have been investigated in accordance with ASTM standards. From the investigations, it has been found that loading of ZrO₂ filler to glass basalt hybrid fibre reinforced composites show superior tensile and hardness behaviour compared to unfilled composites. The increase in ZrO₂ filler to glass basalt hybrid reinforced composites shows high resistance to wear under dry sliding. Various aspects of the fractured surface of the samples have been examined by scanning electron microscopy (SEM) photomicrographs.

Keywords: basalt fibre; dry sliding wear and SEM; epoxy; flexural modulus; flexural strength; glass fibre; hardness; tensile modulus; tensile strength; zirconia.
