Method of molding resin-impregnated fabric layer using release sheet and absorbent sheet inside evacuated bag

A method for producing a fiber reinforced plastic structural component having curved surface sections from a resin pre-impregnated partially cured fabric, comprising the steps of

• a. disposing at least one layer of resin pre-impregnated partially cured fabric on a first mold section having curved portions,
• b. disposing a release-coated fabric on said at least one layer of resin impregnated fabric,
• c. disposing at least one layer of bleeder cloth on said release fabric to draw and hold excess resin from said resin pre-impregnated fabric, said bleeder cloth comprising a textile-like non-woven fabric comprising polyester fibers locked into place by fiber interaction, the fabric having a regular repeating pattern of entangled fiber regions of higher area density than the average area density of the fabric and interconnecting fibers which extend between the dense entangled fiber regions and which are randomly entangled with each other in said regions, said fibers of the fabric being locked into place by a three-dimensional fiber entanglement characterized by a fiber-interlock value due to fiber entanglement of at least 7 with a fiber entanglement completeness of at least 0.5, said values being determined in the absence of binder, and wherein fibers in said regions turn, wind, twist back and forth, and pass about one another in all directions of said regions in such an intricate entanglement that fibers interlock with one another when the fabric is subjected to stress, to thereby provide coherency and strength to the fabric;
• d. disposing second mold section over said at least one layer of bleeder cloth,
• e. applying pressure to all the components in the mold formed by said first and second mold sections, and
• f. evacuating the gases through said release fabric and said at least one layer of bleeder cloth while heating all the components of the mold to completely cure the resin pre-impregnated fabric.
