摘要： A method is proposed for manufacturing a composite material piece of large dimensions and having a high fibre volume ratio (more than 58%) by resin transfer moulding. It consists in compacting strongly a fibrous preform (26) placed in a mould (20), while injecting the resin at a constant preset flow rate, as long as the instantaneous pressure at the inlet of the mould is less than a preset pressure. When this preset pressure is reached, the flow rate is reduced to maintain the pressure at this level, and compacting of the preform (26) is temporarily reduced. The injection flow rate is then brought back to the constant preset flow rate and compacting is increased to start a new cycle.
摘要翻译：提出了通过树脂传递成型制造大尺寸复合材料片并具有高纤维体积比（大于58％）的方法。只要模具入口处的瞬时压力小于预设压力，就将强制地压实放置在模具（20）中的纤维预成型件（26），同时以恒定的预设流速注入树脂。当达到该预设压力时，流量降低以将压力保持在该水平，并且预成型件（26）的压实度暂时降低。然后将注射流量恢复到恒定的预设流速，并且增加压实以开始新的循环。

摘要： Device for the pyrotechnic separation between two elements (2, 4), for example panel-shaped elements. The first element (2) comprises two projecting parts (6, 8) connected to the remainder portion of the element by areas of reduced thickness (10, 12). The projecting parts (6, 8) are secured to the second element (4) by means of screws (30) and nuts (32). A deformable envelope (20) containing a detonating fuse is placed into the cavity (16) formed by the projecting parts (6, 8), the body of the first element (2) and the second element (4). Upon firing, the envelope (20) deforms and causes the rupture at the connection areas (10, 12). The thin areas (10, 12) being close to the extremity of the cavity (16) which is remote from the fixing point of the projecting parts (10, 12) to the second element (4), a greater lever arm and therefore an improved efficiency are obtained. Application to the aeronautical or spatial field.
