  • Patent number: 4647326
    Abstract: 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.

  • Patent number: 4507164
    Abstract: A method and an apparatus are described for making a filamentary web. One or more strands of roving, each composed of multiple filaments, are spread out to increasing extents until the filaments form a band in which they extend unidirectionally and generally parallel to each other, but are not connected with one another. Adhesive strips, threads or other connecting elements are then transported on a carrier into a working station so as to be positioned transverse to the elongation of the band. In the working station, they are transferred to the band and joined to the filaments under application of contact pressure in the nip between cooperating nip rollers. This converts the band into a unitary filamentary web structure in which the filaments are all unidirectionally oriented.
