This work focuses on the preparation of a polymer matrix composite material, consisting of 90 vol% unsaturated polyester (UPs) and 10 vol% polyurethane (PU). The experiment was carried out in two stages. The first stage involved studying the effects of aluminium alloy (Al) mesh on the different ratios (5, 10, 15, and 20 vol%) of a polymer blend. The second stage entailed examining the additional effect of silica fume (SF) particles at different ratios (12 and 16 vol%). The results showed increases in (flexural strength, impact strength, hardness, and thermal conductivity), with higher metal mesh percentages, but when SF was added, thermal conductivity was lower compared to that of mesh, and hardness was higher than that of Al alloy mesh. The maximum values were as follows: B1 for flexural strength (180 MPa at 20 vol% Al alloy mesh, B1 for impact strength (9 kJ/m2) at 20 vol% Al alloy mesh, B3 for hardness (89 at 20 vol% Al alloy mesh and 16 vol%SF), and B1 for thermal conductivity (0.9 W/m x °C at 20 vol% Al alloy mesh).
