車乮用樹脂材料の琭状と今後の動向

摘要

車両用樹脂材料は1960年代から，意匠性，軽量化，高rn機能化などその時代の要求にあわせて増加し，車両重量rnの1割近くを占めるようになってきた．その間，地球環rn境は温暖化による危機が叫ばれ始め，温暖化ガスとしてrnのCO_2の削減が急務となってきている．%To reduce CO_2 exhaust, it is strongly demanded that we should make fuel consumption efficiency better. From the view of weight-reduction directly relating to fuel consumption efficiency, we investigated that approach to plastics and the trend of technique which would be expected hereafter. Though we can see many challenges, we could expect great weight-reduction potential of CFRTP. And from the carbon neutral point of view, we also deliberated the plastics originated from plant.
