Abstract: A hybrid metal and composite spool includes metal rings on an outer diameter of a composite spool shell. Metal rings may include features such as annular or axial dovetail slots. Adhesive layers may be between the metal rings and composite shell which may be connected by a shrink bonded joint. The metal rings may include a single seal tooth ring with an annular radially extending seal tooth. A method for fabricating the spool may include fabricating one or more metal rings with the features therein, positioning the metal rings in place on an outer surface of an uncured composite spool shell of the spool before curing the shell, and curing the shell with the one or more metal rings positioned in place. Alternatively, rings may be heated to a temperature at least sufficient to slide rings over a cured composite shell, and allowed to cool and shrink onto shell.

Abstract translation: 混合金属和复合线轴包括在复合卷轴外壳的外径上的金属环。 金属环可以包括诸如环形或轴向燕尾槽的特征。 粘合剂层可以在金属环和可通过收缩接合连接的复合壳之间。 金属环可以包括具有环形径向延伸的密封齿的单个密封齿环。 制造卷轴的方法可以包括制造具有其特征的一个或多个金属环，在固化壳体之前将金属环定位在卷轴的未固化的复合卷轴外壳的外表面上，并将壳体固化在壳体上 或多个金属环定位就位。 或者，环可以被加热到至少足以将环滑过固化的复合壳体的温度，并允许冷却并收缩到壳体上。
