在汽车制造商宝马AG的莱比锡车身车间，宝马i3在生命周期内考虑乘客安全保护的碳纤维复合材料构件RTM被引入自动优化装配流水线中。作为第一个有着碳纤维结构件的汽车，i3是领先用复合材料顶板及使用再生碳纤维增强的其他部件。电池电动汽车，带着时尚的后铰链的“教练门”，在2013年底在欧洲销售和北美的汽车买家在2014年的春季。但是汽车制造商，包括宝马，现在都看好”多材料汽车应用”，它将满足轻量化带来的挑战！

In automaker BMW AG’s Leipzig Body Shop, the BMW i3’s RTM’d carbon fiber composite components for its Life Module passenger protection cell are brought together in a robotically optimized assembly process. The first production car built with structural carbon composites, the i3 also pioneers the use of a composite roof and other parts reinforced with recycled carbon fiber. The battery electric vehicle, complete with stylish rear-hinged “coach doors,” went on sale in Europe in late 2013 and North American car buyers had their first look in spring 2014. But automakers, including BMW now look to the "multi-material vehicle" to meet the lightweighting challenges
