ABSTRACT:
There is provided a continuous molding method capable of varying a thickness of a prepreg molded article.A molding material10is prepared such that three plies, for example, of prepreg31, 32, 33are laminated with different end face positions on each face of a prepreg laminate20of a carbon fibre or the like, and prepreg peel plies41, 42, 43are arranged continuously to the respective plies of the prepreg31, 32, 33. This molding material10is transformed into a sheet and continuously sent out to a hot press for molding, which is then heated in a post-curing oven for a prescribed period of time for thermosetting. After the molding, the prepreg peel ply40is peeled and removed so that a product whose sectional thickness varies can be obtained.
