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 moulding material which comprises: (a) a structural reinforcement layer comprising a fibrous reinforcement material optionally in combination with a second resin composition; and (b) a surface enhancing layer, for contacting a surface of a mould or tool, comprising a first non-woven fibre carrier in combination with a first resin composition containing a rheology modifier and a curing agent, wherein the first resin composition provides an external mould or tool-contacting surface of the moulding material. The moulding material can be cured to form a moulded article having a high quality surface finish that requires minimal preparation before painting and/or application in its intended use. The moulded article may be provided with sacrificial discontinuous indicator means to assist in uniform removal of a part of the surface enhancing layer of the moulded article for specific applications.
