Development of High-Speed and High-Quality Laser Cutting Process for Fiber Reinforced Plastics

摘要

The ordinary method of KFRP (Kevlar Fiber Reinforced Plastics) trimming in which a cutter was used by a worker needed much time and labor. The working environment was not good due to cutting dust. So we tried to use laser processing in trimming instead of a hand cutter. First we investigated the interaction between three kinds of lasers (CO_2, YAG, and Excimer lasers) and KFRP. Finally we have proposed a new cutting method using CO_2 and Excimer lasers. We have manufactured the optical system and cutting head and carried out high-speed and high-quality cutting.
