Composite pressure-resistant shell of ratchet type metal end frame and forming method of composite pressure-resistant shell

The invention relates to the technical field of composite materials, in particular to a composite material pressure-resistant shell of ratchet type metal end frames and a forming method of the composite material pressure-resistant shell of the ratchet type metal end frames, and the forming method comprises the following steps that the two metal end frames which are oppositely arranged are prepared, and the two metal end frames are installed on a mandrel in a spaced mode; the fibers are wound in the mode that circumferential winding and oblique winding of the ratchets are alternated; carrying out first curing molding to obtain a pressure-resistant shell prefabricated product of the ratchet type metal end frame; machining is carried out, and an inverted trapezoidal groove is formed in the connecting position of the metal end frame and the composite shell; the inverted trapezoidal groove is internally coated with rubber, secondary curing forming is conducted, the outer surfaces of the metal end frames and the co
