Abstract: In this paper, three kinds of vacuum infusion epoxy resin systems, i.e., MERICAN 3311A/B, another domestic product and an imported product, for wind turbine blades were comparatively analyzed. The wettability of these epoxy resin systems for glass fibers were investigated, and the mechanical properties of their composites prepared by vacuum infusion molding process, were also studied. The results show that MERICAN 3311A/B had low viscosity and good wettability to glass fiber, which was satisfactory for vacuum infusion with glass fibers. Accordingly, through testing the mechanical properties of resin fiberglass plates, three kinds of epoxy resin systems all had good mechanical behavior, and the strength and modulus of MERICAN 3311A/B even exceeded the imported product and the other domestic product. Therefore, according to the comprehensive study of the behaviors, MERICAN 3311A/B can fufill the needs of large-scale wind turbine blades, which can be used to manufacture wind turbine blade.

Key words: wind turbine blade, epoxy resin, wettability, mechanical property
