Accessory for molding of articles made of polymeric composite materials

摘要

An accessory for molding of articles made of polymeric composite materials has a frame and composite shape-generating surface fastened to it. Furthermore, in the shape-generating surface an internal source of heating is located, which consists of resistive layer submerged in the insulating structure at the depth h:,where λ - coefficient of thermal conductivity of composite material;T - required temperature of heating;l - length of filament with radius r;N - power of current source;&rgr; - linear resistance of filament;І- maximum breakdown power of current.
