    摘要： A method for manufacturing a multi-resin composite article is provided. The method comprises providing at least one fiber preform in a mold; injecting a plurality of resins into the at least one fiber preform at a plurality of locations on the at least one fiber preform; and forming at least one transition region along a mutual contact surface between the resins. Each of the at least one transition regions is defined by a gradual transition in composition from one of the resins to another of the resins. A multi-resin composite article is also provided. The article comprises: at least one fiber preform; a plurality of resins, wherein the at least one fiber preform is infused with the resins; and at least one transition region extending along a mutual contact surface between respective ones of the resins. A system for manufacturing such a multi-resin composite article is also provided.

    摘要： A fan containment casing includes a core comprising a number of tows. The core has a central region and two end regions. The tows are grouped into a number of bands and form a number of filament-wound radially disposed layers. The bands of tows are interleaved as a number of direct bands and indirect bands along at least a portion of one or more of the layers. A method of forming a fan containment casing includes winding a number of tows on a liner to form a number of radially disposed layers, where each of the layers is continuously connected to at least one adjacent one of the layers across one of the end regions via at least one of the tows.

    摘要： A lightweight, impact-resistant gas turbine blade, such as an aircraft engine fan blade, has an airfoil portion which includes a metal section and at least one foam section which together define a generally airfoil shape. The metal section extends from generally the blade root to generally the blade tip. A composite skin generally completely surrounds, and is bonded to, the metal section and the at-least-one foam section. Preferably, an erosion coating generally completely surrounds, and is bonded to, the composite skin.

    摘要： An airfoil, a fan assembly and an engine include at least one airfoil including a root portion, a body portion and a tip portion. The body portion is configured extending radially outward from the root portion and the tip portion is configured extending radially outward from the root portion and the body portion. The airfoil including a suction and a pressure side coupled together at a leading and a trailing edge and extending therebetween. The airfoil including a compliant tip at the tip portion. The compliant tip extending along at least a portion of the tip portion in a chord-wise direction and a span-wise direction. The compliant tip is configured to provide wave propagation along the tip portion such that critical strain proximate the tip portion and the trailing edge is reduced during a foreign object impact.
