Biomorphic SiC ceramics,a new environmentally friendly type of composite,have been drawing a considerable amount of attention by researchers in recent years. Because of their excellent properties,such as high mechanical strength,high thermal stability,resistance toward oxidation and corrosion,and chemical inertness at high temperatures,SiC ceramic composites have shown great potential in the building construction market. This paper summarized the fabricating methods and mechanisms of the biomorphic SiC ceramics produced from abundant biobased materials such as wood,bamboo,and rice straw. Based on the review of the current research status and obstacles facing these new composites,the authors discussed the future research direction in this area.
