发明名称 Composite molding process utilizing tackified fabric material
摘要 A quantity of fluid resin material is rendered into a flowable state without the use of solvents. The fabric then is beaded with at least one elongate bead of the flowable resin, wherein at least a portion of bead remains on the surface of the fabric to tackify the fabric and facilitate lay-up of the beaded fabric in the composite molding process. The fabric then is laid-up into a molding apparatus, wherein the bead adheres to surfaces in the molding apparatus and assists in positioning of the fabric therein. A further quantity of resin is disposed or injected under pressure into the molding apparatus and into contact with the fabric and contours of the mold. The resin then is cured to form the composite body.
