The invention relates to a process for forming a cured, partially cured or uncured thermosetting material, comprising: an irradiation step wherein the thermosetting material is exposed to electromagnetic radiation which to a significant extent is within the neat-infrared range in such a way that the temperature of the irradiated thermosetting material is brought to between 40~C and 400~C, and a forming step wherein the irradiated thermosetting material is brought into a desired shape, whereby the forming step is executed during and/or subsequent to the irradiation step. The invention also relates to an apparatus for carrying out the said process and to a thermosetting material.
L'invention concerne un procédé permettant le formage d'un matériau thermodurcissant durci, partiellement durci ou non durci. Ce procédé comprend une étape d'irradiation consistant à exposer le matériau thermodurcissant à un rayonnement électromagnétique dont une grande partie se situe dans la gamme infrarouge proche, de manière à élever la température du matériau thermodurcissant irradié dans un intervalle compris entre 40·C et 400·C, et une étape de formage consistant à donner la forme désirée au matériau thermodurcissable, cette étape de formage étant exécutée pendant et/ou après l'étape d'irradiation. L'invention concerne également un dispositif permettant la mise en oeuvre dudit procédé, et un matériau thermodurcissant.
