In this study, the spectra was surface-treated using $Ar^+$ ion beam to improve the tensile property of spectra/vinylester composites. The effect of surface treatment on the tensile property of spectra/vinylester composites was investigated comparing tensile strength and stiffness of surface-treated spectra/vinylester composites with those of untreated spectra/vinylester composites. The results showed that the tensile strength and stiffness of surface-treated s spectra/vinylester composites were 12% and 22% higher than those of untreated spectra/vinylester composites.
