A novel hybrid composite SiC foam/SiC particles/EP (denoted as SiC foam /SiC p /EP), consisting of E‐51 epoxy resin as the matrix, SiC foam and SiC particles as the reinforcements, was prepared in this work. The slurry erosion properties of SiC foam /SiC p /EP composite and SiC foam /EP (SiC foam/epoxy resin) composite were investigated by using a rotating disc rig. It was found out that SiC foam /SiC p /EP exhibited better mechanical and anti‐erosive performance as compared with SiC foam /EP. SiC particle size had great influence on the mechanical and anti‐erosive properties of the hybrid composites. Smaller SiC particles were beneficial to improve the mechanical strength, but inclined to decrease the anti‐erosive performance of the composite. In general, the hybrid composite SiC foam /SiC p /EP can be applied potentially with the excellent anti‐erosive performance under the solid particle erosion conditions. POLYM.
