Quick mast–105 is a well-known epoxy-based adhesive used in fabric reinforcement, bonding of wooden parts and variety of metals. Its mechanical and thermal properties are still limiting factors for extended technological and industrial applications. Enhancement of mechanical, wear and thermal characteristics of this epoxy resin using a cheap filler of CaCO3powder is the focus of the present study. The mechanical properties are demonstrated in terms of the flexural modulus, hardness and impact strength of the reinforced cured compound while thermal properties are presented through thermo gravimetric analysis and thermal conductivity coefficient. Results show that addition of 15% by weight of CaCO3 to the epoxy resin improves the mechanical properties and the thermal resistance of the end product paving the way for wider applications in industry and technology. Wear characteristics show that the reinforced product is suitable for high-speed applications.
