Silicon Carbide-Reinforced Plastic Material

摘要

This material is prepared by mix molding homogeneously a mixture of plastic material with a beta -SiC powder, whose particle size is less than 1 mu , the alpha -SiC content is less than 10%, and whose average long dia/short dia ratio is 1.2 to 1.7. The beta -SiC powder has been washed with HF, dried, and treated with a silane coupling agent. The plastic is from the group of thermosetting, thermoplastic, and heat-resistant resins. The fabrication process comprises 3 steps: dispersing the beta -SiC powder into the plastic and kneading, crushing the kneaded material into fine powder, and finally molding the powder in a metal mold.
