초록

Large composite structures are produced using a vacuum assisted resin transfer molding process. The structures incorporate cores, which may be hollow cells or foam blocks. A plurality of cores, each of which may be wrapped with a fiber material, is arranged in a layer on a mold with a fiber material arranged to form face skins. The assembly is sealed under a vacuum bag to a mold surface. One or more main feeder conduits are provided in communication with a resin distribution network of smaller channels which facilitates flow of uncured resin into and thr...

청구항

[ We claim:] [1.] A composite structure comprising:cores each having a peripheral surface having a top face, a bottom face, and side faces, the cores arranged in a layer with ones of the side faces disposed in opposition to others of the side faces, the layer having an upper surface defined by each top face, and a lower surface defined by each bottom face, each peripheral surface having a configuration to provide channels between at least some of the side faces between adjacent ones of the cores from the upper surface to the lower surface which form a re...
