    Abstract: A method is provided for forming a composite article to have a primary composite structure and an integral secondary composite structure that extends out of a plane defined by the primary composite structure. The method includes laying-up first plies to construct the primary composite structure. The first plies contain continuous reinforcement material and extend from a first zone that will define the primary composite structure into a second zone that will define the secondary composite structure. During laying-up of the first plies, additional plies are interleaved with the first plies within the second zone but not the first zone. The additional plies originate within a build-up zone between the first and second zones and extend therefrom into the second zone. After interleaving the plies, the build-up zone is deformed to orient the second zone and form the secondary composite structure that extends out of the plane defined by the continuous reinforcement material of the first plies.

    Abstract translation: 提供了一种用于形成复合制品以具有主要复合结构和从由主复合结构限定的平面外延伸的整体的次级复合结构的方法。 该方法包括铺设第一层以构造主复合结构。 第一层包含连续的增强材料，并从将限定主复合结构的第一区延伸到将限定次级复合结构的第二区。 在第一层铺设期间，附加层与第二区内的第一层交错而不是第一区。 附加层起始于第一和第二区之间的积聚区，并从其延伸进入第二区。 在层叠之后，堆积区域变形以使第二区域定向并且形成延伸出由第一层的连续增强材料限定的平面的次级复合结构。

    Abstract: Composite fan blade platform includes forward and aft portions and transition portion therebetween. Platform mounting holes extend through increased section thickness in transition portion and conical countersinks centered about centerlines of mounting holes extend into transition portion. Bolts include bolt shanks extending away from boltheads through center bolt holes in conical load spreaders in conical countersink. Boltheads engage conical load spreader. Bolthead is disposed entirely within cylindrical counterbore into top of load spreader and engages shoulder at bottom of cylindrical counterbore. Radial gap between bolthead and cylindrical counterbore surface of cylindrical counterbore may be filled by filler or filler ring. Bolts may join platform supports to disk hooks attached, fixed or joined to, or integral with disk posts of disk. Nuts threaded on threaded inner end of bolt shank may secure bases attached to platform supports to fan blade platform.
