Flaky TiB2 toughened B4C-SiC composite material and preparation method thereof
The invention provides a flaky TiB2 toughened B4C-SiC composite material and a preparation method thereof, and relates to the technical field of ceramic materials. According to the invention, SiB6, carbon black and flaky TiO2 are used as ceramic aggregates, and an ethylene-vinyl acetate copolymer and polyether sulfone are used as binders to prepare the flaky TiB2 toughened B4C-SiC composite material. The fracture toughness of the sheet-shaped TiB2 toughened B4C-SiC composite material can reach 8.2 +/-0.6 MPa.m < 1/2 > or above, and meanwhile, the bending strength of the sheet-shaped TiB2 toughened B4C-SiC composite material can reach 650 +/-28 MPa.
本发明提供了一种片状TiB2增韧B4C‑SiC复合材料及其制备方法，涉及陶瓷材料技术领域。本发明是利用SiB6、碳黑、片状TiO2作为陶瓷骨料，利用乙烯‑醋酸乙烯酯共聚物和聚醚砜作为粘结剂制备出一种片状TiB2增韧B4C‑SiC复合材料。本发明片状TiB2增韧B4C‑SiC复合材料的断裂韧性可以达到8.2±0.6 MPa·m1/2以上，同时其抗弯强度可达650±28 MPa。
