The invention relates to an integrally formed fairing and a preparation method thereof. The integrally formed fairing is prepared by a method of combining mesophase pitch-based carbon fiber prepreg and quartz fiber prepreg. The mesophase pitch-based carbon fiber prepreg cloth is of a sandwich structure formed by mesophase pitch-based carbon fibers and a resin matrix, the quartz fiber prepreg cloth is of a sandwich structure formed by quartz fiber woven cloth and a resin matrix, and the resin matrix is formed by doping fused quartz ceramic in cyanate ester resin. According to the fairing, the production process that two kinds of fiber prepreg cloth are combined is adopted, and optimization of the material performance is achieved. Compared with the prior art, the fairing has the advantages of being high in strength, excellent in heat conduction performance, light in weight, resistant to high temperature and high in stability under the extreme temperature condition.

    本发明涉及一种一体成型的整流罩及其制备方法,使用中间相沥青基碳纤维预浸布与石英纤维预浸布相结合的方法制备。所述中间相沥青基碳纤维预浸布为由中间相沥青基碳纤维与树脂基体形成的夹芯结构,石英纤维预浸布为由石英纤维编织布与树脂基体形成的夹芯结构,所述树脂基体采用氰酸酯树脂中掺杂熔融石英陶瓷组成。所述整流罩使用两种纤维预浸布相结合的生产工艺,实现材料性能的优化。与现有技术相比,本发明所述整流罩在具有高强度、优异的导热性能的同时,还具有质轻、耐高温、极端温度条件下稳定性高的优势。
