| description | The invention discloses a molded part forming method, and relates to the technical field of composite material forming. A specific implementation mode of the method comprises the following steps: S1, laying a third layer of prepreg on the surface of a preform forming mold, and vacuumizing and compacting; s2, laying a fourth layer of prepreg on the third layer of prepreg; s3, a demolding film is laid on the fourth layer of prepreg; S4, curing is carried out; s5, after curing, removing the prefabricated body forming die to form a prefabricated body; s6, laying a first layer of prepreg on the core material of the molded part, and vacuumizing and compacting; s7, laying a second layer of prepreg on the first layer of prepreg, and vacuumizing and compacting; s8, laying a prefabricated body on the second layer of prepreg; s9, mold closing is conducted; step S10, curing is carried out; and S11, demolding is conducted, and a workpiece is formed. The method can reduce the cloth clamping fault in the mold closing area o |
