    Abstract: There is provided a process for preparing a prepreg (31) comprising reinforcement fibre (13) impregnated with a thermosetting resin matrix (20), said process comprising: a) providing a layer (24) of reinforcement fibre (13); b) applying a layer (24) of a first thermosetting resin matrix (20) to the first surface (15) of the layer (24) of reinforcement fibre (13) and bringing the first surface (15) of the layer (24) of reinforcement fibre (13) into contact with the support surface (5) of a first continuous belt (3), so that the layer (24) of first thermosetting resin matrix (20) is positioned between, and in contact with, the first surface (15) of the layer (24) of reinforcement fibre (13) and the support surface (5) of the first continuous belt (3); c) heating the layer (24) of first thermosetting resin matrix (20) applied to the first surface (15) of the layer (24) of reinforcement fibre (13) in contact with the support surface (5) of the first continuous belt (3); d) bringing the second surface (17) of the layer (24) of reinforcement fibre (13) into contact with the support surface 9) of a second continuous belt (7); e) heating the layer (24) of first thermosetting resin matrix (20) and the layer (24) of reinforcement fibre (13) between the support surfaces of the first and second continuous belts (3, 7) so that the first thermosetting resin matrix (20) impregnates the layer (24) of reinforcement fibre (13); f) cooling the layer (24) of reinforcement fibre (13) impregnated with the first thermosetting resin matrix (20) between the support surfaces of the first and second continuous belts (3, 7); and g) removing the layer (24) of reinforcement fibre (13) impregnated with the first thermosetting resin matrix (20) from the support surfaces of the first and second continuous belts (3, 7).

    Abstract: An improved surface finish on articles moulded from prepregs is obtained by providing a surface finishing film on the surface of the prepreg and a surface venting layer on the surface of the surface finishing film in which the finishing film comprises a flowable tacky resin and the venting layer contains perforations which allow passage of the resin through the venting layer to provide removable adhesion between the surface of the mould and the moulding composition during moulding.

    Abstract: This invention relates to a use of a non-woven thermoplastic resin in combination with a curable moulding material comprising a fibrous reinforcement material and a thermoset resin material by bringing the thermoplastic resin in contact with the curable moulding material during or following assembly of the moulding material. The thermoplastic resin has a melting point below the gel temperature of the thermoset resin material to reduce the void fraction and increase the ILSS of a cured moulding manufactured from said moulding material forming a laminate structure in comparison to a cured moulding manufactured from said moulding material in which the fabric is absent forming the laminate structure.
