KONTINUIERLICHES PULTRUSIONSVERFAHREN ZUR HERSTELLUNG VON HOCHLEISTUNGS-STRUKTURPROFILEN

摘要

The invention provides a continuous pultrusion process for producing high-performance 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 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.
