Abstract: Moulding material that includes a layer of fibrous reinforcing material having one surface on which a first layer of a resin partially impregnates the fibrous material and a further resin layer located on the opposite surface which retains in position surface fibers of the fibrous material. The further resin layer is of lower weight than the first layer and is formed as an openwork structure with a solid part and spaces through which the fibrous material is exposed.

Abstract: An uncured composite product having a middle fibrous reinforcement, a thermosetting-resin based layer and a hardening-agent based layer for the thermosetting resin. The thermosetting-resin based layer is placed on one side of the fibrous reinforcement and the hardening-agent based layer is placed on the other side so that the fibrous reinforcement forms a physical barrier between the thermosetting resin and the hardener. When heated, the thermosetting resin and/or hardener flows across the physical barrier to provide mixing and resultant curing.

Abstract: An uncured fiber reinforced assembly that includes a reinforcement layer containing a fibrous material and at least one highly reactive curing agent. A matrix film layer is applied to the reinforcement layer so that it does not substantially impregnate the reinforcement layer. The matrix film layer includes at least one uncured epoxy resin and at least one latent epoxy curing agent. The assembly is designed for use in making snowboards and skis.

Abstract: The flow of resin during the molding of composite articles is controlled by forming areas of immobilized resin during the infusion of resin into the fibrous body. The immobilized resin is formed using an immobilization agent that interacts with the infused resin to form a high viscosity resin barrier that is effective in blocking the flow of non-immobilized resin. The barriers of immobilized resin are located within the fibrous body so as to control the flow of non-immobilized resin during the molding process to prevent or least reduce resin depletion and to selectively block resin flow from the mold.

Abstract: A resin composition comprising: (i) one or more polymerisable liquid thermoset resin components; (ii) optionally one or more curing agents for said one or more polymerisable liquid resin components; and (iii) at least one gelator, wherein said gelator interacts within said composition to form a gel at ambient temperatures, said gel being thermally reversible such that the gelled composition can undergo a transition from the gelled state to a state of lower viscosity when the composition is treated to facilitate the cure of said polymerisable resin component.

Abstract: A fire resistant laminate for application to a core structure (12) to form a sandwich panel (10) having fire resistant face sheets (14 & 16). The laminate includes a fire protection (18) in which at least one layer of fibers (22) is embedded within a cured inorganic polymer matrix (24). The laminate further includes an adhesive layer (20) for bonding to the core structure.

Abstract: Aqueous solutions of inorganic nitrate salts are used to accelerate the gelling of epoxy gelcoat resins without adversely affecting the glass transition temperature of the finally cured gelcoat. The aqueous accelerants may be used to accelerate gelling of gelcoats that are formed during initial fabrication of composite parts. The aqueous acclerants are also useful for shortening the gel time of gelcoats that are intended for use in repairing damaged structures.
