The method involves supplying a profile which is wound round a winding structure (13). The stresses are present in the profile as a result of the winding. The profile comprises several fibers extending along one another, which are embedded in a partially cured thermosetting matrix material. A heat treatment is carried out on the profile, by means of a heat treatment device, while the profile is wound round the winding structure. The matrix material is post-cured, during heat treatment. The glass-transition temperature of the matrix material is increased as a result of the heat treatment and the temperature to which the profile is exposed during the heat treatment remains below the glass-transition temperature. The stresses remain constant and the shape is retained both in cross-section as well as radius of curvature of the profile, in the stress-free state, despite the heat treatment and despite winding the profile round the winding structure prior to the heat treatment.

A pulling device is provided for a pultrusion device, having at least one clamping device that can be moved in a pultrusion direction. The clamping device is designed to frictionally seize a pultruded profiled strand to be conveyed, in order to apply a tensile force to the profiled strand. The clamping device has at least three clamping jaws that can be moved in relation to each other, for peripherally clamping the profiled strand.

The invention relates to a shut-off flap (26) for a motor vehicle shut-off device, notably for a device for shutting off an air inlet in the front face of a motor vehicle, comprising a flap body (28), the flap body (28) being at least partially made of a fibre reinforced composite material, notably one that uses continuous reinforcing fibres (42, 44). The invention also relates to a motor vehicle shut-off device comprising such a flap and to methods of manufacturing this flap and this shut-off device for a motor vehicle.

A resin impregnating device (1) is used in a method for producing a reinforcing bar and has a chamber for holding a liquid thermoplastic resin. A plurality of guide plates (4A-4C) is arranged in the chamber along a traveling direction of a plurality of strands of reinforcing fiber material (Fb). Through holes (41) in two of the guide plates (4A, 4C) guide or spread the strands of the reinforcing fiber material Fb away from each other, and a single through hole (42) in an intermediate one of the guide plates (4B) guides or converges all the strands of the reinforcing fiber material (Fb) towards each other.

An assembly (113) for composite manufacture is provided. The assembly comprises a cured resin impregnated reinforcement material (112) comprising a fibre component and a resin matrix component, in which the resin matrix component comprises polyurethane, the assembly having a length to width ratio of at least 5:1, and the assembly defining a longitudinal direction (L) along its length; and a peel ply (116) in contact with the cured resin impregnated reinforcement material (112), the peel ply (116) comprising a woven layer having a plurality of longitudinal fibres (118) extending in the longitudinal direction (L); and a plurality of transverse fibres (120) extending in a transverse direction (T) normal to the longitudinal direction (L); in which the areal density of the plurality of transverse fibres (120) is higher than the areal density of the plurality of longitudinal fibres (118).

A method of manufacturing a coated article comprises injecting a feedstock with a polymer resin to provide a resin-injected feedstock, pulling the resin-injected feedstock through a pultrusion die to form a pultrusion substrate having one or more profile surfaces, adhering an adhesive material comprising a thermoplastic polyurethane onto at least a portion the one or more profile surfaces to form one or more adhesive tie layers on the pultrusion substrate, and applying one or more coating materials onto the one or more adhesive tie layers to form one or more coating layers on the one or more adhesive tie layers to provide a coated pultrusion article, wherein an adhesion strength between the one or more coating layers and the one or more adhesive tie layers is higher than a corresponding adhesion strength would be between the one or more coating layers and the pultrusion substrate.
