Methods of making fiber reinforced composite articles are described. The methods may include treating fibers with a sizing composition that includes a polymerization compound, and introducing the treated fibers to a pre-polymerized composition. The combination of the treated fibers and pre-polymerized composition may then undergo a temperature adjustment to a polymerization temperature at which the pre-polymerized composition polymerizes into a plastic around the fibers to form the fiber-reinforced composite article. Techniques for introducing the treated fibers to the pre-polymerized composition may include pultrusion, filament winding, reactive injection molding (RIM), structural reactive injection molding (SRIM), resin transfer molding (RTM), vacuum-assisted resin transfer molding (VARTM), long fiber injection (LFI), sheet molding compound (SMC) molding, bulk molding compound (BMC) molding, a spray-up application, and/or a hand lay-up application, among other techniques.
本文描述了制造纤维增强复合材料制品的方法。这些方法可包括用包括聚合化合物的上浆组合物处理纤维,并将处理过的纤维引入预聚合组合物。然后将处理过的纤维和预聚合组合物的组合物进行温度调节,使其达到聚合温度,在此温度下预聚合组合物聚合成纤维周围的塑料,形成纤维增强复合材料制品。将处理过的纤维引入预聚合组合物的技术可包括拉挤、绕丝、反应性注塑成型(RIM)、结构反应性注塑成型(SRIM)、树脂传递成型(RTM)、真空辅助树脂传递成型(VARTM)、长纤维注射(LFI)、片状模塑化合物(SMC)成型、块状模塑化合物(BMC)成型、喷射应用和/或手糊应用等。
