    Abstract: A prepreg or semipreg precursor comprising a fibre reinforcement and a resin composition fused thereto, the resin composition containing at least one epoxy resin and a latent curing agent, wherein the epoxy resin and the latent curing agent form a solid phase at ambient temperature, the latent curing agent forming a discrete phase within the epoxy resin. The stabilized uncured resin composition and prepregs and semipregs incorporating the same are easy to handle, have desirable curing temperatures and show good outlife at ambient to mid range temperatures.

    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.

    Abstract: There is provided a surfacing material comprising an ultraviolet (UV) resistant polymer layer, a thermocurable or thermoplastic resin layer and a fibrous support, wherein a first surface of the UV resistant polymer layer forms an outermost surface of the surfacing material and the second surface of the UV resistant polymer layer contacts a first surface of the thermocurable or thermoplastic resin layer, and the second surface of the thermocurable or thermoplastic resin layer contacts a first surface of the fibrous support. There is also provided methods of forming cured composite structures having an ultraviolet resistant outer surface utilising a surfacing material of the invention, and cured composite structures incorporating a UV resistant surfacing layer of the invention.
