Title
(EN) PROCESS FOR MANUFACTURING A SHAPED OBJECT THROUGH FILAMENT WINDING
(FR) PROCÉDÉ DE FABRICATION D'UN OBJET FAÇONNÉ PAR ENROULEMENT DE FILAMENT
Abstract
(EN) The invention pertains to a process for manufacturing a shaped object through a winding process comprising the steps of - winding resin-containing fiber under tension to form a shaped fibrous object, the resin comprising at least 50 wt.% of polyester derived from an aliphatic polyol with 2-15 carbon atoms and an aliphatic polycarboxylic acid with 3 to 15 carbon atoms, calculated on the polymer constituents of the resin, - subjecting the shaped fibrous object to a curing step. In one embodiment, the resin-containing fibers are provided through a process comprising the steps of - contacting fiber with a liquid resin composition, the resin composition comprising polyester derived from an aliphatic polyol with 2-15 carbon atoms and an aliphatic polycarboxylic acid with 3 to 15 carbon atoms, to obtain resin-containing fibers, - subjecting the resin-containing fibers to a drying step, the drying step being carried out until the resin-containing fibers are tacky and the resin-containing fiber has a diluent content of at most 25 wt.%, calculated on the weight of resin composition in the resin-containing fiber. Tacky fibers obtainable by this intermediate process are also claimed, as is the shaped fibrous object that can be obtained by the process according to the invention.
(FR) L'invention concerne un procédé de fabrication d'un objet façonné par un procédé d'enroulement comprenant les étapes consistant à - enrouler une fibre contenant de la résine sous tension pour former un objet fibreux façonné, la résine comprenant au moins 50 % en poids de polyester dérivé d'un polyol aliphatique avec 2 à 15 atomes de carbone et un acide polycarboxylique aliphatique ayant 3 à 15 atomes de carbone, calculé sur les constituants polymères de la résine, - soumettre l'objet fibreux façonné à une étape de durcissement. Dans un mode de réalisation, les fibres contenant de la résine sont fournies par un procédé comprenant les étapes consistant à - mettre en contact une fibre avec une composition de résine liquide, la composition de résine comprenant un polyester dérivé d'un polyol aliphatique avec 2 à 15 atomes de carbone et un acide polycarboxylique aliphatique ayant de 3 à 15 atomes de carbone, pour obtenir des fibres contenant de la résine, - soumettre les fibres contenant de la résine à une étape de séchage, l'étape de séchage étant réalisée jusqu'à ce que les fibres contenant de la résine soient collantes et que la fibre contenant de la résine ait une teneur en diluant d'au plus 25 % en poids, calculée sur la base du poids de la composition de résine dans la fibre contenant de la résine. L'invention revendique également des fibres collantes pouvant être obtenues par ce procédé intermédiaire, ainsi que l'objet fibreux façonné qui peut être obtenu par le procédé selon l'invention.
