マテリアルリサイクルとLCA

摘要

We have been participating in the Japanese national project" R&D of CFRP for lightening weight of automobile" organized by METI and NEDO since 2003fy. This paper presents the recycling technique and LCA of CFRP as one item of the project. First of all, domination to the steel car of a lightened car using CFRP was shown from a viewpoint of LCA, and it was clarified that the recycling of CFRP was effective. The injection molding and the polypropylene were selected, and the influence of recycled fiber content and recycling frequency on the properties of recycled parts was investigated.%本稿では，経済産業省の地球温暖化防止新技術プログラムとして行われているプロジェクト「自動車軽量化炭素繊維強化複合材料の研究開発」（2003～2007年度，運営機関：新エネルギー・産業技術総合開発機構）の一項目である「自動車用CFRP（Carbon Fiber Reinforced Plastics）のリサイクル技術」について概説する．
