A unitary vacuum bag (4) for forming of fiber reinforced composite article having molded in resin distribution means (10) formed to a specific article. The vacuum bag (4) is constructed upon that mold which forms the base for the construction of the desired fiber reinforced composite article. The bag (4) contains an open sided, resilient main distribution conduit (10) running laterally along the long axes of the vacuum bag with branch conduits (10) to provide for long distance flow of resin to all parts of the composite article and elastomeric tube receptacles (20). A multiplicity of cross channels (14) are formed on the inner surface of the bag from a pattern of dots (16), covering most of the area under which the fiber lay up is placed within the mold. A model on the mold is used to form a vacuum bag (4) from an elastic material and the vacuum bag is used to form a composite article.

Poche à vide individuelle (4) pour la formation d'un article composite à fibres renforcées présentant des moyens de distribution (10) moulés en résine formés selon l'article spécifique. Ladite poche à vide (4) est formée sur le moule constituant la base de la structure de l'article composite à fibres renforcées. Ladite poche (4) contient un conduit de distribution principal (10) élastique ouvert sur les côtés s'étendant latéralement le long des grands axes de la poche à vide et des conduits de distribution (10) de manière à produire un flux de résine sur une longue distance vers toutes les parties de l'article composite et les réceptacles de tubes élastomères (20). Une multiplicité de canaux transversaux (14) est formée sur la surface interne de la poche à partir d'un motif de points (16) couvrant la majorité de la surface sous laquelle le renfort en fibres est placé dans le moule. Un modèle sur le moule est utilisé pour former une poche de vide (4) à partir d'une matière élastique, ladite poche étant utilisée pour former un article composite.
