摘要： A method for impregnating a fibrous preform by injection or infusion, the method including the steps of providing a mold having at least two portions, said mold presenting an inlet orifice and a vent orifice placed on opposite sides of the mold; placing a fibrous preform in a portion of the mold; placing a seal in a passage formed between an inside wall of the mold and the fibrous preform, said passage extending substantially along the direction extending between the opposite sides of the mold; closing the mold so that the two portions of the mold co-operate with the seal in such a manner as to shut off said passage; and impregnating the fibrous preform with an impregnation material.

摘要： The present disclosure concerns a method for manufacturing a composite panel including a cellular central core interposed between two skins. The manufacturing method includes the steps of manufacture of an element with a cellular structure comprising a cellular core structure interposed between two layers of structural plies intended to form the skins, positioning of the element with a cellular structure within a mold, formation of drains on either side of the cellular core structure, infusion of the element with a cellular structure so as to impregnate it with a resin, carrying out a draining of the resin through the drains in the element with a cellular structure during the infusion step, the drains having a geometry configured to provide draining, and polymerization of the impregnated element with a cellular structure to form the composite panel.

摘要： In a fiber reinforced composite member molding apparatus comprising a lower mold having a cavity, an upper mold having a core which, in a mold clamping state, engages with the cavity in the lower mold and thereby clamps layered prepreg, and heat sources for heating the layered prepreg through the lower mold and the upper mold, and adapted to mold a fiber reinforced composite member from the layered prepreg by applying pressure while heating resin in the layered prepreg between the lower mold and the upper mold by the heat sources, the lower mold is equipped with a cavity heat-escape prevention portion and the upper mold is equipped with a core heat-escape prevention portion. During heating for molding, escape of heat from the periphery of the cavity of the upper mold and the periphery of the core of the lower mold can be prevented, which allows a fiber reinforced composite member to be molded with almost no defects such as wrinkles.
