ABSTRACT Epoxy resin is widely used in fiber‐reinforced composite structures, but its application high‐end projects limited due to the relatively brittle characteristics caused by high crosslink density. In this paper, reaction process of ZnO surface treated with silane coupling agent described, and toughening mechanism nano‐ZnO on matrix elaborated. A three‐level three‐factor experimental strategy has been designed, orthogonal tests were conducted investigate influence different design parameters, such as solid–liquid epoxy ratio (SLR), mass contents catalytic (2E4MI). With results three‐point bending (3P‐bending) hardness beams prepared twill woven fabrics, response analysis based statistics was carried out evaluate optimize parameters. Results show that, for beam optimized configuration, maximum load, stiffness, increased 40.02%, 51.25%, 58.18%, respectively.
