Abstract
Methods are described for activating a glass fiber or flake to participate in polymerizing a resin. The methods may include sizing the glass fiber or flake with a sizing composition that includes a solution containing a polymerization initiator, and activating the polymerization initiator by forming a free radical moiety on the polymerization initiator that can initiate the polymerization of the resin. Additional methods of making a glass reinforced composite are described. The methods may include sizing glass fibers or flakes with a sizing composition that includes a solution containing a polymerization initiator, forming a free radical moiety on the polymerization initiator to make activated glass fibers or flakes, and contacting the activated glass fibers or flakes with a polymer resin. The activated glass fibers or flakes initiate the polymerization of the resin around the glass fibers or flakes to form the glass reinforced composite.
