Title
(EN) PROCESS FOR FABRICATION OF FIBER COMPOSITES USING DUAL-CURE FREE-FROM 3D-PRINTED TAILORED FIBER PLACEMENT PREFORM
(FR) PROCÉDÉ DE FABRICATION DE COMPOSITES DE FIBRES À L'AIDE D'UNE PRÉFORME DE PLACEMENT DE FIBRES PERSONNALISÉES IMPRIMÉES EN 3D DE FORME LIBRE À DOUBLE DURCISSEMENT
Abstract
(EN)
A method for generating a thermo set Fiber- Reinforced Polymer (FRP) composite preform includes: dispensing, from a print head of a 3D-printer, a dual-cure resin coated fiber including a dual-cure resin with a ultra-violet (UV)-curable component and a thermally-curable component; curing, during the dispensing of the dual-cure resin coated fiber, the UV-curable component with a UV light source such that the dual-cure resin coated fiber is partially cured and contacting lengths of the partially-cured dual-cure resin coated fiber bond together; and positioning the print head during the dispensing and curing of the dual-cure resin coated fiber to three- dimensionally print the thermoset FRP composite preform.
(FR)
La présente invention concerne un procédé permettant de générer une préforme composite thermodurcissable de polymère renforcé par des fibres (FRP pour Fiber-Reinforced Polymer) qui consiste : à distribuer, à partir d'une tête d'impression d'une imprimante 3D, une fibre revêtue de résine à double durcissement comprenant une résine à double durcissement avec un composant durcissable aux ultraviolets (UV pour Ultra-Violet) et un composant thermodurcissable ; à faire durcir, pendant la distribution de la fibre revêtue de résine à double durcissement, le composant durcissable aux UV avec une source de lumière UV de telle sorte que la fibre revêtue de résine à double durcissement soit partiellement durcie et à mettre en contact des longueurs de la liaison de fibre revêtue de résine à double durcissement partiellement durcie ensemble ; et à positionner la tête d'impression pendant la distribution et le durcissement de la fibre revêtue de résine à double durcissement pour imprimer en trois dimensions la préforme composite thermodurcissable de polymère FRP.
