Mechanical propereties and moisture absorption of epoxy composite mixed with amorphous and crystalline silica from rice husk

Thermosetting epoxies are low-density polymers with excellent adhesion, mechanical properties, and resistance to environmental degradation. They are widely used as molds and castings for manufacturing, protective coatings, and reinforcement material for aircraft. However, polymer brittleness is a ma...
