| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系 === 86 === Because of the experience and improvement of manufacturing
technology,resin transfer molding has the potential to fabricat
complex load-bearing component . 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.
