ABSTRACT:
Multiple resin transfer molding is the simultaneous injection of differing esins in fiber preforms with or without a separation layer. The flow of the resins is controlled by varying the permeabilities of the preforms and the separation layer. The method produces multifunctional hybrid composites made of multilayered preforms and multiple resins. A fundamental advantage of the invention is the simplification of the manufacturing process.
