Experimental study of the effect of temperature and velocity in channel forming of polyvinyl chloride composite reinforced by 3D-fiberglass with an aluminum middle layer

Abstract In this paper, the stamp forming process of a U-shaped cross-section channel with sharp corners composite laminates including aluminum sheet and polyvinyl chloride (PVC) reinforced 3D-fiberglass was investigated. The were produced by manual layup arrangement fibers different angles [0°/90°] [± 45°] degrees using hot press. samples carried out at temperatures 25, 80, 120, 160°C velocities punch. effect parameters configuration, temperature, speed on spring-back formed required force evaluated. results showed that as temperature increased, decreased sharply. lowest obtained for laminate 45°, Al, ± layout which equal to 0.7KN. Also, increase in angle has been reduced, is 3 8 degrees. Finally, it concluded increasing decrease more pronounced higher temperatures. Graphical abstract
