Controlling the properties of epoxy composites filled with brick dust

Treatment of the filler surface with a silane dressing agent, ensuring the chemical interaction on the filler–binder interface, and ultrasonic treatment of the compound enhance the physicomechanical properties of the epoxy composite: The failure stress and bending elastic modulus increase by a factor of 2–3. Considerable (2.5- fold) increase in the impact resilience even at 50% filling should be particularly noted. Introduction of modified brick dust enhances the heat resistance and thermal conductivity of the epoxy composite.
