In this article, the influence of process parameters on warm deep drawing of PVC/fiberglass composite laminates (FRP) is investigated through the experimental tests. Fiberglass reinforced polymer (PVC) composite laminate sheets are new emerging materials that have many potential applications. FRP/composites provide high strength to weight ratios exceeding those of aluminum or steel. For the experimental tests, composite samples with [0/90]2, [0/90]4, [-30/30]2, [-30/30]4 lay ups were produced in using film stacking procedure. Statistical analyses based on Taguchi's method are used to reduce the number of experiments and to investigate the effect of process variables on the output results. The results show that the two variables of temperature and blank holder force have the most influence on output parameters. Furthermore they demonstrate that a high interaction between the forming temperature and blank-holder force is required to remove the wrinkling.
