Abstract
A device for continuously manufacturing an FRP square pipe includes a core having a long length for laminating prepreg sheets thereto, and prepreg sheets are supplied from prepreg-sheet laminating devices and to said core covered with a release film, said laminated sheets laminated into the shape of a square pipe. Said core has an outer diameter size smaller than the inner diameter size of the square pipe to be manufactured. A pre-expansion device expands said laminated prepreg sheets to the shape of a square pipe having a predetermined inner diameter size, and a hot press device heats and pressurizes the pipe. The pipe is then additionally heated in a postcure furnace to complete the forming process. A pulling device arranged downstream of a cramp device pulls out said square pipe intermittently. A cutter not shown cuts said square pipe to produce the desired product.
