However , the cycle time for resin transfer molding is still long . For thefabrication of a large structure , it becomes the major problem to cut down the cycle time in order to compete with other process. In this study , we demonstrate the usage of the preheater to reduce the cure time and achieve the uniformity of cure phase for the complex load-bear-ing component. The process of themethod is to heat the resin by the preheater before it wasinjected into the mold.According to the experimental results it was found that, the molding results are batter for the cureif the resin preheated temperature close to the fiber preheatedtemperature . The cure time was about reduced 30% and the uniformity of cure phase was satisfaction.
