A resin transfer molding preform is disclosed comprising a formation of fiber reinforcement material and a web in direct contact with the formation and encapsulating at least a portion thereof, i.e., the web secured or fixed to the fiber reinforcement material mechanically or by adhesion, etc. A method of making certain of the resin transfer molding preforms of the invention comprises spraying random chopped fiber reinforcement material onto a forming member while drawing a vacuum through the forming member, applying a web over at least a portion of the fiber formation while it remains on the forming member, and compressing the fiber reinforcement material under the web to reduce the loft thereof. Also disclosed is a resin transfer molding process employing a preform according to the invention.
A resin transfer molding process for making FRP parts, which process comprises placing a fiber reinforcement material preform into a molding cavity of a resin transfer molding tool, substantially closing said molding tool and introducing resin into said cavity, wherein said preform comprises a fiber reinforcement material formation and a web in direct contact with said formation and encapsulating at least a portion of said formation, wherein said web is soluble in said resin.
A resin transfer molding process for making FRP parts employing a fiber reinforcement material, which process comprises the following steps:
