Experimental Study of the Roll Forming of PVC / Glass Fabric Composite Laminates

Roll forming of amorphous PVC based composite laminates were studied in this paper for the first time. For this, [0/90]6 and [45/-45]6 lay-ups of this composite laminates with dimensions of 80×12 cm were fabricated using film stacking and hot pressing processes. The suitable forming temperatures of the composites were determined and then, the laminates were roll formed at 170ᵒC with a single stand and also multi stand roll forming process into channel sections. Geometrical defects including warping, flange waviness and spring back of the roll formed profiles were evaluated. Finally it was concluded that [0/90]6 lay-up results in very lower defects in comparison with [45/-45]6 lay-up, and also the final stand of roll forming process has dominant role on the defects of multi stand roll forming.
