Title (EN) A PROCESS FOR PRODUCING A COMPOSITE ARTICLE
(FR) PROCÉDÉ DE PRODUCTION D'UN ARTICLE COMPOSITE
Abstract:
(EN) Process for producing a composite material comprising depositing a prepreg containing a radiation initiated curing agent onto a mould using automated apparatus and applying heat and second source radiation to at least partially cure the prepreg at least simultaneously with the deposition of the prepreg. Also epoxy resin formulations of a mixture of a liquid epoxy resin and a solid or semi-solid epoxy resin containing a photoinitiator are used as the matrix in prepregs which are cured or partially cured by radiation to avoid the need for thermal cure in an oven. The formulation is particularly useful in the production of wind turbine blades especially in an automated process. Additionally an automated tape laying apparatus comprising compaction device, a heat source and a second radiation source.
(FR) Cette invention concerne des formulations de résine époxy à base d'un mélange constitué d'une résine époxy liquide et d'une résine époxy solide ou semi-solide contenant un photo-initiateur qui sont utilisées à titre de matrice dans des pré-imprégnés qui sont durcis ou partiellement durcis par rayonnement afin d'éviter de recourir à un durcissement thermique dans un four. La formulation est particulièrement utile dans la production de pales d'éoliennes, notamment dans un procédé automatisé.
