Abstract:
A method for forming a compound material, said method comprising:a pinching step of pinching and fixing the upstream end and the downstream end of a composite material reinforced with continuous fibers having waviness; a heating/pressurizing step of heating and pressurizing the pinched and fixed composite material intermittently; and a moving step of releasing the compound material and sending said material to the downstream direction after termination of the heating/pressurizing step; wherein during said pinching step, a tension toward the downstream advancing direction is provided to the downstream end of said composite material, and during said moving step, the amount of movement of said compound material at the downstream side is set to be greater than the amount of movement of said compound material at the upstream side, thereby straightening said fibers in the compound material linearly to reduce said waviness in said fibers.
