A method of manufacturing a shape from a composite material by applying laminations impregnated with plastic resin to a positive mold. At least one cellular, cellular-core layer is applied into the neutral zone of the laminations and embedded into them while the laminations are being built up. The cellular layer is a rigid foam. The cellular-core or honeycomb layer has the axis of each cell radial to that of the shape and can be single, double, or multiple. If double or multiple it may have an interior connective layer consisting of plastic, foil, glass cloth, non-woven carbon-fiber fabric, polyimide, or woven or non-woven fabric impregnated with plastic resin. The cellular-core or honeycomb layer is intended to make the shape more stable and flexurally strong. |
