The invention discloses a method for connecting fiber reinforced ceramic matrix composite special-shaped structural parts, and relates to the technical field of composites. According to the invention, on one hand, the problem of easy agglomeration during direct addition of the nanoscale reinforcement is overcome, and on the other hand, the content of the nanoscale reinforcement in the connecting layer can be remarkably increased, and finally, the connecting strength is remarkably improved. Layered ceramic (such as Ti3SiC2 and the like) has a hexagonal crystal structure, has the characteristics of ceramic and metal, such as high modulus, high fracture toughness, good thermal shock resistance and the like, and can improve the defect of high brittleness of traditional ceramic to a certain extent as a connecting layer material. And meanwhile, the self-propagating reaction of the Ti-Si-C system at high temperature is beneficial to reducing the connection temperature, the thickness of the Ti3SiC2 layer generated in
