Special-shaped beam product prepreg forming process

The invention provides a special-shaped beam product prepreg forming process. The special-shaped beam product prepreg forming process comprises the steps of firstly, clamping and fixing a core mold by using a rotary supporting device; then forming a product base; then removing the core mold; forming a product base composite part; clamping and fixing the product base composite part, and winding the prepreg for the second time; then carrying out second thermocuring; winding the prepreg for the third time and carrying out thermal curing for the third time; winding the prepreg for the fourth time; and carrying out fourth thermocuring to form a product. According to the forming process provided by the invention, the forming process steps of the special-shaped beam product are reasonably decomposed, demolding is very convenient, the product quality is not influenced after demolding, and a structural foundation is not laid for subsequent production. Moreover, prepreg winding, thermocuring, demolding and embedded par
