Résumé : |
The low cost, relatively high fibre strength, and low density of polypropylene (PP) fibres make them an attractive candidate for reinforcing low-cost composite materials for various applications. The use of particles in fibre-reinforced composite structures usually improves the strength of the basic material. Alumina (Al2O3), with its unique properties, has been used to improve the composite material's properties. It is crucial to determine the appropriate concentration of Al2O3 particles that can be added to Polypropylene whisker/epoxy composites to get the required mechanical and physical properties. In this study lamination 80:20 resin was used as a matrix material to prepare a Polypropylene whisker (3%wt.) reinforced lamination 80:20 resin (PP/resin) composite. The composite materials were manufactured by hand lay-up method. Different concentrations (1, 3, 5, 7 & 10wt.%) of alumina (Al2O3) particles, were used to reinforce the composite. The composite materials are prepared with standard sizes according to the tests, the tests include mechanical tests (tensile, impact, and hardness test) and physical tests (water absorption and density). The tests results showed an improvement in tensile strength, elongation, toughness, fracture toughness, hardness and density, while the water absorption diminishes concerning an increase in the concentration of the Al2O3 particles. The tensile strength, elongation, elastic modulus, hardness and density improved from (17 MPa, 1.3%, 1.13GPa, 70 Shore D and 0.93gm/cm3) respectively for neat lamina and reach the maximum value (34.5 MPa, 3.1%, 1.47 GPa, 83 Shore D and 1.01 gm/cm3) respectively at (3%wt. PP and 10%wt. Al2O3), while the toughness and fracture toughness improved from (3.8 KJ/m2 and 0.06 MPa.m1/2) respectively for neat lamina and reach the maximum value (23.1 KJ/m2 and 0.19 MPa.m1/2) respectively at (3%wt. PP and 7%wt. Al2O3). |
