Abstract: The invention relates to a particulate curing component for a thermosetting resin, the particulate curing component comprising particles of a solid resin, wherein a curative for the thermosetting resin is dispersed within the particles of solid resin. The invention also relates to methods of forming particulate curing components and compositions comprising particulate curing components.

Abstract: The present invention defines a pultrusion apparatus. The apparatus comprises a portion for receiving fibres, a portion for injecting resin into the fibres, a portion for impregnating the resin injected fibres, and a portion for shaping the impregnated fibres, wherein the fibres, following their passage through the receiving portion, converge in the resin injection portion to receive the resin and the resin flows outwards following injection as the fibres progress from the injection portion through the impregnation portion.

Abstract: The invention provides a continuous pultrusion process for producing structural profiles wherein a) one or more textile sheets are impregnated with a resin composition comprising a combination of (i) at least one epoxy resin which is a tri- or tetrafunctional epoxy resin and (ii) a curing agent system comprising at least two types of reactive groups of different reactivity b) the impregnated textile sheets are subjected to heat to cause a partial reaction between the at least one epoxy resin and the curing agent system, so that the viscosity of the resin composition is increased, and c) the partially reacted impregnated resin composition is gelled using heat and/or pressure.
