A Study on the Tensile Behavior of Spectra Composite with Surface Treatment of Spectra Fibers

스펙트라 섬유의 표면처리에 따른 스펙트라 복합재의 인장특성에 관한 연구

We investigated the surface treatment of spectra fibers to improve tensile properties of spectra/vinylester composites. The spectra fibers were surface-treated using $\textrm{Ar}^{+}$ ion beam under oxygen environment. The treatment effect of spectra fibers on the tensile properties of spectra/vinylester composites was determined comparing the residual strength of surface-treated spectra/vinylester composites with that of untreated spectra/vinylester composites. It was found that the residual strength was improved 15% by the surface treatment of spectra fibers.
