An aqueous adhesive composition for treating a reinforcing fiber for bonding to a thermosetting polymer matrix and products made therefrom such as power transmission belts. The adhesive composition includes: water as the solvent or dispersing medium; a polyelectrolyte co-curable with the polymer matrix; a primer material compatible with the fiber and co-curable with the polyelectrolyte; and optionally a rubber curative compatible with the polyelectrolyte and the polymer matrix. A fiber-reinforced, composite polymer system may thus include a thermosetting polymer matrix, a reinforcing fiber embedded therein, and an adhesive composition coating the fiber; the adhesive composition including a polyelectrolyte co-curable with the polymer matrix and a primer material compatible with the fiber and co-curable with the polyelectrolyte. The adhesive composition may include a curative compatible with the polyelectrolyte. In one preferred embodiment, the invention is an aqueous adhesive composition including water, an epoxy resin, a maleated polybutadiene derivative, and a curative.
