Outline of Final Research Achievements |
We have developed a novel manufacturing method of Carbon fiber reinforced plastics (CFRP). That is, a carbon fiber woven fabric was immersed in an electrodeposition solution, and the resin was deposited and impregnated by energization. In this method, it was shown that a three-dimensional CFRP can be integrally molded, and curvilinear arrangement of carbon fibers can be easily applied. Furthermore, it was shown that the strength of CFRP was improved by applying the cellulose nanofiber dispersion on the surface after electrodeposition. Particularly, by applying aqueous electrodeposition solution, the hydrophobic treatment of cellulose nanofibers, which has been inevitable in the previous method, became unnecessary.

Academic Significance and Societal Importance of the Research Achievements |
航空機や自動車,スポーツ用品などには,高強度と軽量性を有するCFRPが広く用いられるようになったが,製造には高温・高圧が必要でエネルギ消費が多い。本研究では、電着液中で樹脂を含浸させる方法を開発し、立体的なCFRPの一体成形を可能にした。また、CFRP内の炭素繊維を曲線配置することによる荷重伝達の効率化、木材など再生可能な天然資源から精製されるセルロースナノファイバーを利用した更なる高強度化が可能であることなどを示した。
