据美国《高技术产业》杂志1989年第4期报道,由布莱克斯堡弗吉利亚综合工艺学院化学工程教授唐·贝尔德(Don Baird)研制的一种新工艺,可以生产出强度更高、刚性更好、价格更便宜的复合材料,并就这种新工艺于1988年11月申请了一项专利。 贝尔德的工艺方法是把液晶聚合物丸掺入也是聚合物丸形式的热塑性塑料基体中,通过挤压使液晶聚合物形成纤维,从而省掉了生产复合材料中的一道浸渍工序。这种复合材料进 According to a report by the U.S. High Technology Industry Magazine, No. 4, 1989, a new process developed by Don Baird, a professor of chemical engineering at Virginia Tech, Blacksburg, produces higher-strength, Rigid, cheaper composites and filed a patent for the new process in November 1988. Baird’s process is to incorporate liquid crystalline polymer pellets in a thermoplastic matrix, also in the form of polymer pellets, by extruding the liquid crystalline polymer into fibers, thereby eliminating the need for an impregnation step in the production of composite materials. This composite material into
