Abstract: The domestic abrasive grade SiC particles with average diameter of 65 μm were selected and reshaped by using a fluidized bed air jet mill. High volume fraction SiCp/Al composites with the as-received and reshaped SiC particles were prepared by pressureless infiltration in order to investigate the effect of the particle shaping process on the microstructure and mechanical properties of the composites. The results show that the shaping process makes the reshaped SiC particles more spherical, with the average diameter reducing to 52 μm and the packing density increasing from 1.577 g/cm3 to 1.846 g/cm3. The volume fraction of SiC particles in the composites is increased from 53.27% to 61.09%, which is the main reason for the improvement of the mechanical properties of the composites. Accordingly, the flexural strength and elastic modulus of the composite can be improved from 376 MPa to 431 MPa and from 196 GPa to 219 GPa, respectively, showing an enhanced ability to resist small deformation. The results of the finite element analysis showed that the stress and strain distributions of the composite with the reshaped SiC particles are more uniform, without obvious stress concentration phenomenon.
