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.
