Title (EN) MOULDING METHOD
(FR) PROCEDE DE MOULAGE
Abstract:
(EN) A method of moulding complex composite articles having skin portions containing fibres to be injected with a resin and a core portion comprises providing one or more galleries in the core or fibre skin and injecting resin into the gallery or galleries whereby it is rapidly transmitted to all portions of the skin. The galleries overcome the resistance to flow created by the capillary nature of the fibrous layer and enable more rapid mould cycles to be employed and more complex articles therefore to be moulded.
(FR) Un procédé servant au moulage d'articles composites complexes comportant des parties d'enveloppe qui contiennent des fibres destinées à être injectées au moyen d'une résine, et une partie noyau, consiste à former une ou plusieurs galeries dans le noyau ou dans l'enveloppe fibreuse et à injecter la résine dans la ou les galerie(s) par lesquelles la résine se transmet rapidement à toute les parties de l'enveloppe. Les galeries permettent de surmonter la résistance à l'écoulement créée par la capillarité de la couche fibreuse, d'utiliser des cycles de moulage plus rapides et donc de mouler des articles plus complexes.
