Abstract

This paper indicates that lightened automobiles are effective for mitigation of environmental burdens in the transport sector, and proposes that applying CFRP (carbon fiber reinforced plastics) to panel, plate and structural members for lightening the automobiles is one of the solutions. Annual world energy consumption will increase 4.5 times compared with the present due to Chinese motorization. So, we consider that energy saving and CO/sub 2/ reduction in the transport sector is important. We estimate that the basic unit of energy consumption by an ultra lightened automobile is one-third compared with the present when applying CFRP to an automobile. In the following, in 2050, the amount of energy saving by applying CFRP to Chinese automobiles is about 450 Mtoe (mega ton of oil equivalent) which is 150% of the current annual Japanese total energy consumption, compared with BAU (business as usual) case. We consider the effect of ultra-lightened automobiles on the environmental problems due to Chinese motorization. At once, we identify that discontinuous CF (carbon fiber)/TP (thermoplastics) preforming for a composite can be realized in experiment, and discuss that improvement in mechanical properties, mitigation of environmental burdens and cost saving of CFRP parts compared with lightened metal parts in mass production is necessary for producing an ultra lightened automobile.
亚洲机动化带来的轻量化汽车对环境问题的影响
本文指出,汽车轻量化对减轻交通运输部门的环境负担是有效的,并提出将CFRP(碳纤维增强塑料)应用于汽车的面板、板和结构件轻量化是解决方案之一。由于中国的机动化,世界每年的能源消耗将比现在增加4.5倍。因此,我们认为节能和减少运输部门的CO/sub / 2是很重要的。我们估计,超轻量化汽车的基本单位能耗是目前使用碳纤维增强塑料的汽车的三分之一。在接下来的文章中,2050年,中国汽车使用CFRP节能量约为4.5亿吨油当量,这是目前日本每年总能耗的150%,与BAU(照常经营)情况相比。我们考虑了超轻量化汽车对中国机动化带来的环境问题的影响。首先,我们确定了复合材料的不连续CF(碳纤维)/TP(热塑性塑料)预成型是可以在实验中实现的,并讨论了CFRP零件的力学性能的改善,减轻环境负担和节省成本,相对于轻量化金属零件的量产是生产超轻量化汽车的必要条件。
