Abstract: The paper analyze development process of the advanced resin matrix composite materials forming technology, that is low pressure molding, pultrusion process, molding, filament winding forming process, placement molding process, molding process of RTM, and analyze the key technology in the development process, to study the evolvement of advanced composite material molding process, so as to explore the future development direction of forming resin based composite material technology.
From the fiber reinforced composite started by the military and engineering circles.
So the improvement of the process becomes the key to development process of advanced composite materials, the next step.
RTM is the resin is injected into the closed mold infiltration technique for improving material and curing molding technology, is developing rapidly in recent years, suitable varieties in batch, high quality advanced composite products.
