Abstract
A continuous forming method and device for an H-shaped FRP member for forming semi-hardened preimpregnated members produced by impregnating thermosetting resin to carbon fiber or glass fiber and the like into a predetermined H-shape. The forming device comprises of a device for mounting a plural number of bobbins having strip-shaped preimpregnated material spooled thereto, providing tension when pulling the impregnated material out from the bobbin. The device the shapes the preimpregnated material to a predetermined H-shape that feeds release films from four sides of upper, lower, left and right. The device then provides heat and pressure to the preimpregnated material from said four sides with a heating furnace for after-curing the preimpregnated material. The device then hauls and holds the preimpregnated material for cutting the cured product.
