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.
