    摘要: A tool comprising a support section, a plurality of tool sections beatable around the core section to define one or more tool surfaces on which structure material is beatable to be molded to form a composite structure, the support section and enclosure means being sealingly engagable to enclose the tool sections and structure material therebetween, thus allowing air to be withdrawn from between the enclosure means and the support section as part of the cure process of the structure material. Sealing the enclosure means directly against the support section obviates the need for the tool sections to be sealingly interconnected.

    摘要: Radius fillers (390) for composite structures (30), composite structures (30) that include radius fillers (390), and systems (100) and methods (400) of forming the same are disclosed herein. The methods (400) include determining a transverse cross-sectional shape of an elongate void (38) space, which extends within a transition region (40) that is defined by a plurality of plies (48) of composite material (31), and determining a material property field of the transition region (40). The methods (400) further include forming the radius filler (390) by combining a plurality of lengths of composite tape (160) to define a radius filler (390) cross-sectional shape, which corresponds to the transverse cross-sectional shape of the elongate void (38) space, and orienting a plurality of lengths of reinforcing fiber (90) in each of the plurality of lengths of composite tape (160) based, at least in part, on the material property field of the transition region (420). The radius fillers (390) include radius fillers (390) with selectively oriented reinforcing fibers (90). The composite structures (30) include the radius fillers (390).

    摘要: The present invention relates to a jig for the manufacture, by means of injection and curing processes, of preforms of composite material frames for aircraft fuselages by using the RTM (resin transfer molding) technology. Two preforms are thus manufactured, one with a C shaped section and another with a L shaped section, together with the preforms of the stabilization ribs for stabilizing the web of the frames and the preform of the roving or staple fiber to cover the gap between the C shaped preform and the L shaped preform. Theses preforms are previously manufactured by any known process for manufacturing preforms. According to a second aspect, the present invention relates to a method of manufacturing composite material load frames for aircraft.
