ABSTRACT:
An apparatus1for continuously forming an FRP square pipe comprises a long core10for laminating prepreg sheets, and to this core10are fed prepreg sheets from prepreg laminating devices20, 30, 40and50with a release film interposed between the core, so as to be laminated into square pipe form. The core10has an outer diameter size smaller than the inner diameter size of the square pipe to be formed. The outer circumference of the square pipe is wrapped with a tape-like film fed from a tape-like release film wrapping device200in spiral fashion, and the work is heated and pressed in a hot press100.The work is then subjected to additional heating in a postcure furnace110to form the FRP square pipe. The square pipe is intermittently pulled by a puller130disposed downstream of a clamp120.The pipe is then cut to predetermined lengths by a cutter not shown to be completed as a product.
