Composite material and preparation method thereof
The invention discloses a composite material and a preparation method thereof. The composite material comprises a brittle material and a plastic material. A nano-scale and/or micron-scale hole structure is formed on the surface of the brittle material, the plastic material is attached to the surface, part of the plastic material is embedded into the hole structure, the shrinkage coefficient of theplastic material is larger than that of the brittle material, the fracture toughness of the plastic material is larger than that of the brittle material, and the plastic material forms shrinkage stress on the brittle material.
本发明公开了一种复合材料及其制备方法。该复合材料包括脆性材料和塑性材料，在所述脆性材料的表面形成纳米级和/或微米级的孔洞结构，所述塑性材料附着在所述表面上，部分所述塑性材料嵌入所述孔洞结构内，所述塑性材料的收缩系数大于所述脆性材料的收缩系数，所述塑性材料的断裂韧性大于所述脆性材料的断裂韧性，所述塑性材料对所述脆性材料形成收缩应力。
