A method of forming a continuous composite structure includes the steps of predetermining relative proportions of a liquid resin forming material, a catalyst, and a inhibitor from respective reservoir (32, 33, 34) based on the ambient temperature and a porous blanket. The predetermined proportions are recirculated independently substantially continuously and coordinated at preselected rates. The predetermined proportions are simultaneously withdrawn and continuously mixed in a chamber (39) having a dispensing outlet (40). A pool (46) of the mixture is formed on the blanket (44) and a leading edge (68) is advanced substantially immediately into permanent contact with a preselected final surface and adhered thereto. Part of the catalyzed and inhibited resin forming material migrates through the blanket to form a continuous resin matrix therein.

Un procédé de formage d'une structure composite continue comprend les étapes suivantes: on détermine au préalable les proportions relatives d'une matière de formage en résine liquide, d'un catalyseur et d'un inhibiteur contenus dans un réservoir respectif (32, 33, 34) en fonction de la température ambiante et d'une couverture poreuse. On met en recirculation les proportions prédéterminées indépendamment de manière sensiblement continue à des débits présélectionnés et coordonnés. On retire simultanément les proportions et on les mélange en continu dans une chambre (39) pourvue d'un orifice (40) de sortie/distribution. Une masse commune (46) du mélange est formé sur la couverture (44) et on fait avancer sensiblement immédiatement le bord avant (68) de ladite couverture en contact permanent avec une surface finale prédéfinie, ledit bord avant étant collé à cette dernière. Une partie de la matière de formage en résine catalysée et inhibée migre dans la couverture pour former dans cette dernière une matrice en résine continue.
