Preparation method of two-dimensional silicon carbide/silicon carbide composite material nut
The invention relates to a preparation method of a composite fastener, in particular to a preparation method of a two-dimensional silicon carbide/silicon carbide composite nut. By means of optimizing the preform type, shaping and preparation process, introducing B4C self-healing components and the like, the density uniformity and mechanical property of the product are remarkably improved, the service life of the product in a high-temperature environment is remarkably prolonged, the preparation period is shortened, and the cost is saved. The method can be applied to connection and assembly of composite material products under the conditions of ultrahigh temperature, oxidation environment and high bearing capacity.
本发明涉及一种复合材料紧固件制备方法，尤其涉及一种二维碳化硅/碳化硅复合材螺母制备方法。通过优化预制体类型、定型及制备工艺、引入B4C自愈合组元等手段，显著提高产品密度均匀性、力学性能和高温环境下的使用寿命，并且缩短制备周期，节约成本。可应用于超高温、氧化环境和高承载条件下复合材料产品的连接装配。
