Abstract

A method and apparatus for manufacturing fiber-reinforced, composite materials relies on one or more processes improving over conventional forming, filling, and processing techniques. A homogeneous resin-stitching process provides for resin stitching for using only 5-20 percent of the rovings in a preform as wetted rovings, cured to maintain a stitching together of the structure. A resin-packet transfer process provides infusion of resins from directly beside a wall of a preform, rather than passing resins throughout the longitudinal length of fibers in a perform. A cyclic vacuum bagging process alternately applied over pressure and outside vacuum to a vacuum bag process, thus relieving pressure, and later, optionally, applying pressure to improve structural strength. Relieving pressure tends to improve (reduce) porosity.
