无论是用机器还是手工制造玻璃纤维增强塑料,都要求玻璃纤维容易被树脂基体所湿润。良好的浸润性意味着树脂能迅速地、均匀地、顺利地浸入并湿润玻璃纤维,充分地包覆玻璃纤维。这不仅能使玻璃纤维增强塑料具有良好的物理、力学性能和较好的外观,而且能缩短成型周期,以便将模具数量和操作空间保持在最小的限度,提高生产率。因此,玻璃纤维被树脂浸渍时间的测定是个重要的课题。 Whether using machines or hand-made glass fiber reinforced plastics, glass fibers are required to be easily wetted by the resin matrix. Good wettability means that the resin can quickly, evenly and smoothly dipping and wetting the glass fibers to fully cover the glass fibers. This not only makes glass fiber reinforced plastics have good physical, mechanical properties and good appearance, but also shorten the molding cycle, in order to maintain the minimum number of molds and operating space, improve productivity. Therefore, the measurement of the glass fiber impregnated with resin is an important issue.
