  • Fibers such as glass fibers, are commonly used as reinforcements for synthetic polymer composites. These fiber reinforced composites are desirable for their combination of light weight and strength and are useful in a variety of applications including automobile components and housings for computers.
  • thermoset resin is incorporated before the heating step so that when heated, the thermoset resin flows across the fibers and acts as a thermoset binder when cured.
  • One method of resin binder incorporation is known as the "wet laid" process involving the formation of an aqueous mixture of chopped glass fibers and resin binder, usually under agitation in a mixing tank. The resulting mixture may then be poured onto a porous mold or screen where suction is applied to remove liquid content.
  • Another wet laid process involves depositing chopped fibers on a mold, spraying the fibers with an aqueous composition containing the resin binder. Alternatively, the chopped fiber can be sprayed with the aqueous composition while they are being chopped and deposited on the mold. The final step in all these processes is to heat the fibers on the mold causing the resin binder to flow and set.
