Ceramic matrix composite heat shield and preparation method thereof
The invention discloses a ceramic matrix composite heat insulation screen and a preparation method thereof. The preparation method comprises the following steps: preparing fiber cloth by taking carbon-fiber-containing bundles as raw materials; preparing inner and outer molds of the shaping mold by adopting a high-temperature-resistant material; winding the fiber cloth on an inner mold of a shaping mold, clamping and fixing the fiber cloth by adopting a correcting mold and a connecting piece, and sewing the inner mold, the fiber cloth and an outer mold into a whole, so that the wound fiber cloth is a fiber preform; sequentially depositing a boron nitride interface layer and a silicon carbide ceramic matrix on the surface of the fiber preform to obtain a heat shield blank, processing the heat shield blank to obtain a ceramic-based composite material heat shield semi-finished product, and then continuously depositing silicon carbide on the surface of the ceramic-based composite material heat shield semi-finished product to obtain the ceramic-based composite material heat shield. The ceramic matrix composite heat shield can effectively solve the problems that an existing heat shield is large in weight and poor in high temperature resistance.
本发明公开了一种陶瓷基复合材料隔热屏及其制备方法，包括以下步骤：以含碳纤维束为原料制成纤维布；采用耐高温材料制备定型模具的内外模；将纤维布缠绕在定型模具的内模上，并采用校型模具和连接件将纤维布夹持固定后将内模、纤维布和外模缝合为一体，缠绕的纤维布即为纤维预制体；将纤维预制体表面依次沉积氮化硼界面层和碳化硅陶瓷基体，制得隔热屏坯料并进行加工，制得陶瓷基复合材料隔热屏半成品，然后继续在陶瓷基复合材料隔热屏半成品表面沉积碳化硅，制得陶瓷基复合材料隔热屏。该陶瓷基复合材料隔热屏可有效解决现有的隔热屏存在的重量大、耐高温性能差的问题。
