  • The absorption characteristics of polyaryl amide-fibers/epoxy and carbon-fibers/epoxy composite radiated by continuous wave laser beam at of 1.319μm were obtained by means of double integrating spheres-photodiode system and microanalysis of recovery specimen.When laser power intensity increases before composite ablation,the absorptive of both the composites slowly decreases.It changes from 0.6 to 0.55 for polyaryl amide-fibers/epoxy composite and from 0.85 to 0.8 for carbon-fibers/epoxy composite.When ablation appears on the composite,the absorptivity of polyaryl amide-fibers/epoxy composite rapidly increases.However,it change little for carbon-fibers/epoxy composite.The results show that ablation has obvious effect on the absorption characteristics of polyaryl amide-fibers/epoxy composite and has little effect on carbon-fibers/epoxy composite.
