石英纤维增强环氧树脂基复合材料的激光烧蚀行为
Laser ablation behavior of quartz fiber reinforced epoxy resin matrix composites
摘要
Abstract
Quartz fiber reinforced epoxy resin matrix composites were prepared using epoxy resin as the matrix and quartz fiber as the reinforcement.The study investigated the irradiation effect of high-energy continuous laser with different power densities on quartz fiber reinforced epoxy resin matrix composites.The study analyzed the effects of laser with power densities of 100 W/cm2,500 W/cm2,and 1 000 W/cm2 on the macroscopic and microscopic morphology and the mass ablation rate of irradiated samples.Through the temperature evolution data and resin pyrol-ysis threshold model,the ablation behavior was further analyzed.Results indicates that after laser irradiation on the surface of composites,the deposited energy causes epoxy resin matrix pyrolysis.As the laser power density increa-ses,the degree of epoxy resin matrix pyrolysis increases,the ablation region on the surface of the composites contin-ues to expand,and the mass ablation rate increases,the damage to the composites intensifies.The generation of gas and residual carbon through epoxy resin matrix pyrolysis play a role in energy consumption,shielding lasers and blocking heat.The composites have a certain resistance to laser ablation.关键词
