Abstract: Composite material that contain epoxy resin which is toughened and strengthened with thermoplastic materials and a blend of insoluble particles. The uncured matrix resins include an epoxy resin component, a soluble thermoplastic component, a curing agent and an insoluble particulate component composed of elastic particles and rigid particles. The uncured resin matrix is combined with a fibrous reinforcement and cured/molded to form composite materials that may be used for structural applications, such as primary structures in aircraft.

Abstract: A tape for use in automated tape laying machines that includes a multi-layer substrate composed of a plastic layer that includes at least one plastic film having an outer film surface and an inner film surface. The plastic film is adhered to a fibrous layer so that the inner surface of the fibrous layer is bonded to the inner film surface. An uncured composite material layer composed of a fibrous reinforcement and an uncured resin matrix is releasably adhered to either the plastic layer surface or the outer fiber layer surface to provide a tape suitable for use in an automatic tape layer.
