摘要： A method of impregnating a fiber preform with an impregnation composition, includes applying a liquid on a structure, the structure including a chamber in which a fiber preform for impregnating is present, the chamber being defined between a rigid support on which the fiber preform is placed and a wall, the wall having a face situated facing the fiber preform; and an impregnation composition for impregnating the fiber preform, the impregnation composition being present in the chamber; the liquid being applied against the wall on its side opposite from the chamber, the wall being configured so that its face situated facing the fiber preform conserves its shape during the application of the liquid, the applied liquid enabling sufficient pressure to be created to move the wall towards the rigid support and impregnate the fiber preform with the impregnation composition.

摘要： A fiber structure made as a single piece by multilayer weaving using a method including weaving warp yarns of at least a first set of layers of warp yarns with weft yarns including at least some that are woven with extra length so as to have warp yarn end portions available that extend beyond the zone of weaving, the warp yarn end portions being returned to be woven with warp yarns by being reinserted in layers of warp yarns, and a hollow, or tubular, portion being formed by looping the first woven set of layers of warp yarns back onto itself and applying traction to the ends of the reinserted weft yarns so that a fiber preform for a part including a hollow portion can be obtained as a single piece.
摘要翻译：一种纤维结构体，通过使用包括至少第一组经纱层编织经纱的方法通过多层织造而制成单件，纬纱包括至少一些以额外长度织造的纬纱，以便具有经纱端部可用的方式延伸超过织造区域，经纱端部通过重新插入经纱层而被返回以经纱织造，并且中空或管状部分是通过将第一组编织层经纱回到自身上并将牵引力重新插入纬纱的端部，使得可以获得用于包括中空部分的部分的纤维预制件作为单件。

摘要： A method is provided of bonding together at least two parts. The method includes assembling together at least two parts and at least one adhesive layer, the adhesive being configured so that its adhesive power increases on heating as a result of it polymerizing, at least one of the parts being made of composite material or of metal, the adhesive layer being present, after assembly, between the parts, the assembled together parts and the adhesive being present in a chamber defined by a wall, the wall having an inside face situated facing a first part present between the adhesive layer and the wall, the first part being intended to be bonded to a second part and only a fraction of the second part being present inside the chamber; and applying a liquid against the wall on its side opposite from the chamber.
摘要翻译：提供了将至少两个部分结合在一起的方法。所述方法包括将至少两个部分和至少一个粘合剂层组装在一起，所述粘合剂构造成使得其粘合力由于其聚合而在加热时增加，所述部分中的至少一个由复合材料或金属制成，粘合剂层在组装之后存在于部件之间，组装在一起的部件和粘合剂存在于由壁限定的室中，壁具有面向位于粘合剂层和壁之间的第一部分的内表面，第一部分旨在结合到第二部分，并且仅第二部分的一部分存在于腔室内; 以及在与所述腔室相对的一侧在所述壁上施加液体。
