    摘要： The present disclosure is directed to a method of forming a composite component. The method includes laying one or more layers of uncured composite material onto a mandrel. The mandrel which includes a plurality of conductive media dispersed in a thermoplastic material. An electric current is supplied to the mandrel to resistively heat the one or more layers of uncured composite material to a temperature sufficient to cure the one or more layers of uncured composite material to form a cured composite component. The mandrel is removed from the cured composite component.

    摘要： A method and an article of manufacture are disclosed for reinforcing various structures, such as pipes, piles, walls, tanks, silos, chimneys, and the like, constructed from various materials including steel, concrete, masonry, wood, plastics, and the like. Some of the various structures may be used to transport water, gas, oil, and the like. One or multiple layers of various material sheets, each sheet having substantially the same or different properties, may be impregnated with resin and wrapped around or attached to the surface of a structure to be reinforced or to the surface of a spacer shell surrounding the structure and subjected to heat to cure the resin and to bond the reinforcement sheets to the structure or the spacer shell. The multiple layers together constitute a heat-cured structure reinforcement wrap (HRW) to reinforce the structure against external and internal loads, such as weight, impact load, blast load, internal pressure, ballistic load, and the like.

    摘要： Apparatus and methods are disclosed for manufacture of a composite rotor blade spar having non-uniform wall thickness. Tooling for manufacturing include a first mold defining a first mold surface and a second mold comprising a rigid layer and a heated layer secured to the rigid layer and defining a second mold surface. A plurality of heating elements embedded in the second mold are activated according to a plurality of different temperature progressions effective to cure portions of the uncured composite blade spar positioned between the first and second mold surfaces coextensive with each heating element of the plurality of heating elements. In some embodiments, the second mold defines a root portion and first and second branch portions. A shear web is placed between the first and second branch portions and is bonded to a blade spar skin surrounding the second mold during curing of the blade spar skin.
