在汽車制造商寶馬AG的萊比錫車身車間，寶馬i3在生命周期內考慮乘客安全保護的碳纖維復合材料構件RTM被引入自動優(yōu)化裝配流水線中。作為第一個有著碳纖維結構件的汽車，i3是領先用復合材料頂板及使用再生碳纖維增強的其他部件。電池電動汽車，帶著時尚的后鉸鏈的“教練門”，在2013年底在歐洲銷售和北美的汽車買家在2014年的春季。但是汽車制造商，包括寶馬，現在都看好”多材料汽車應用”，它將滿足輕量化帶來的挑戰(zhàn)！

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.
