    Abstract: A self-adhesive prepreg comprising a fibre reinforcement layer having a first side and a second side, wherein the first side of the fibre reinforcement layer has been pre-impregnated with a self-adhesive resin composition. The self-adhesive may be used as a structural reinforcement and is especially adapted for direct bonding to oily steel or galvanized steel in the automotive, aerospace and other sheet metal fabrication industries.

    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: The invention relates to a prepreg comprising a structural layer of conductive fibres comprising thermosetting resin in the interstices, and a first outer layer of resin comprising thermosetting resin, and comprising a population of conductive free filaments located at the interface between the structural layer and the outer resin layer which, when cured under elevated temperature, produces a cured composite material comprising a cured structural layer of packed conductive fibres and a first outer layer of cured resin, the outer layer of cured resin, comprising a proportion of the population of conductive free filaments dispersed therein, and to a process for manufacturing prepregs wherein the electrically conductive fibres pass a fibre disrupting means to cause a proportion of the fibres on an external face of the sheet to become free filaments.
