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.

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.

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.

It is known that ion-assisted reaction method is effective for the surface modification of polymers. The surface treatment of Spectra fibers using the ion-assisted reaction method was investigated in the present study The Spectra fibers were treated by $Ar^{+}$ / ion irradiation under oxygen environment. The treatment was carried out at different $Ar^{+}$ ion doses. The$ Ar^{+ }$ /ion doses used were $6$\times$10^{15}$ , $1$\times$10^{16}$ , $5$\times$10^{16}$ , $1$\times$10^{17}$ / ions/$\m^2$. Optimal $Ar^{+}$ ion dose in the treatment of Spectra fibers was determined by measuring the tensile strength and modulus of Spectra/vinylester composites as a function of ion dose. It was found that the optimal ion dose was $1$\times$10^{16}$ions/$\m^2$. It was also found from the scanning electron microscope examination that the surface-treatment improved adhesion between fibers and vinylester resin.
