Abstract: In one aspect, there is a method of making a pre-cured laminate having a total number of plies in a mold (190), the mold (190) having a periphery (198) defined by a forward edge (198a), an aft edge (198b), and outboard ends (198c, 198d). The method includes selecting a first plurality of resin impregnated plies (173) that continuously extend beyond the periphery (189) of the mold (190), the first plurality of resin impregnated plies (173) includes at least 50 percent of the total number of plies; laying the plies in a mold (190); compacting the plies in a mold (190); and pre-curing the plies to form a pre-cured laminate, which can extend beyond the periphery (198) of the mold (190). In an embodiment, a pre-cured laminate includes a first plurality of resin impregnated plies (173) that continuously extend beyond the periphery (198) of the mold (190), the first plurality of resin impregnated plies (173) includes at least 50 percent of the total number of plies.

Abstract: In one aspect, there is a rib assembly (155) for an aircraft wing including a rib web (230) having a top and a bottom, the rib web includes a first laminate (232), a second laminate (234), and a honeycomb panel (236) having an array of large cells disposed between the first laminate (232) and the second laminate (234), each cell having a width of at least 1 cm; and a plurality of skin flanges (240) for fixedly attaching the rib web (230) to a skin of the wing, each skin flange (240) has a base member (242s) having a first portion (242f) and a second portion (242d) and a vertical member (2421) extending from the base member (242s). The plurality of skin flanges (240) can be attached to the top and the bottom of the rib web (230) such that the second portion (242d) of the base member (242s) and the vertical member (2421) are attached to the rib web (230).

Abstract translation: 在一个方面，存在用于飞机机翼的肋组件（155），其包括具有顶部和底部的肋条腹板（230），肋条腹板包括第一层压板（232），第二层压板（234）和 蜂窝板（236），其具有设置在第一层压板（232）和第二层压板（234）之间的大单元阵列，每个单元的宽度至少为1cm; 以及用于将肋条腹板230固定地连接到机翼蒙皮上的多个蒙皮凸缘240，每个蒙皮凸缘240具有基座构件242s，该基座构件242s具有第一部分242f和第二部分 242d）和从基座构件（242s）延伸的垂直构件（2421）。 多个皮肤凸缘（240）可以被附接到肋条腹板（230）的顶部和底部，使得基部构件（242s）的第二部分（242d）和竖直构件（2421）被附接到肋条 肋网（230）。
