  • 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.

  • The use of Spectra fibers as fiber cloth is increasing because of their excellent impact resistance. However, a major limitation on the use of Spectra fibers is a chemical inertness. In this Study, Spectra fibers were surface-treated using Ar$^{+}$ ion beam under oxygen environment to improve the tensile property of Spectra/vinylester composites. The effect of surface treatment of Spectra fibers on the tensile property of Spectra/vinylester composites was determined from tensile tests using Spectra/vinylester composite specimens with and without a hole. It was found that the tensile stiffness and strength of surface-treated case were 22% and 17% higher than those of untreated case for specimens with no hole. The maximum load of surface-treated case was about 15% higher than that of untreated case for specimens with a hole.
