The research was carried out applying the materials produced by the pressure infiltration method of ceramic preforms made of Al2O3 particles of 3-6m with the liquid EN AC-44200 Al alloy. The research was aimed at determining the composite resistance to dynamic loads, taking into account the volume of reinforcing particles (from 10 to 40% by volume) at an ambient of 23°C and at elevated temperatures to a maximum of 300°C. The results of this study were referred to the unreinforced matrix EN AC-44200 and to its hardness and tensile strength. Based on microscopic studies, an analysis and description of crack mechanics of the tested materials were performed. Structural analysis of a fracture surface, material structures under the crack surfaces of the matrix and cracking of the reinforcing particles were performed.}, type={Artykuły / Articles}, title={Impact Strength of Composite Materials Based on EN AC-44200 Matrix Reinforced with Al2O3 Particles}, URL={http://journals.pan.pl/Content/102051/PDF/afe-2017-0094.pdf}, doi={10.1515/afe-2017-0094}, keywords={Composites, Aluminum oxide particles, Impact strength, tensile strength, Squeeze casting}, }
