采用长纤维热塑性塑料（LFT）筋与玻璃纤维布筋复合成型的方法设计了汽车侧面碰撞梁（SIB）。LFT肋设计在连续纤维增强SIB的中心。考虑20/80和50/50的不同90°（纬）/0°（经）比率的织造织物织物以评估复合SIB。进行有限元模拟以预测SIB的失效行为。由50/50比例的机织物片制成的SIB以45°层压并通过将单向带放置在凸缘上而另外增强，其在压缩下表现出最佳的性能值，与钢制SIB相当。
Long fiber thermoplastics (LFT) ribs co-molded with woven glass fabric prepregs were considered to design an automotive side impact beam (SIB). The LFT ribs were designed to locate at the center of the continous fiber reinfoced SIB. The woven fabric prepregs of different 90°(Weft)/0°(Warp) ratios of 20/80 and 50/50 were considered to evaluate the composite SIB. A finite element simulation was conducted to predict the failure behavior of the SIB. The SIB made of woven fabric prepregs with 50/50 ratio which were laminated with 45° and additionally reinforced by placing the unidirectional tapes on the flange showed the best performance value under compression, comparable to steel-made SIB.
