Abstract

The invention comprises a process for impregnating components with polymerizable impregnants which are liquid at room temperature or can be liquefied by heating and are cured by combined use of heat and high-energy radiation, wherein the components are impregnated at ambient temperature or in a preheated state and, after impregnation, are heated in the impregnant until partial gelation occurs, are treated with high-energy radiation before full curing and are then fully cured by thermal means.
