  • Patent number: 9777593
    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.

  • Publication number: 20170225407
    Abstract: An automated fiber placement (AFP) system includes a tool head with a compaction roller and a first variable heat source. The compaction roller is configured to receive at least one of a fiber and a plurality of fibers formed as a laydown tape, and is controlled to apply the laydown tape to a workpiece at a predetermined speed and direction. The first variable heat source is configured to apply a first amount of heat to the laydown tape. The first amount of heat applied is related to the predetermined speed. The AFP system further includes a second variable heat source configured to apply a second amount of heat to the workpiece. The second amount of heat applied is related to at least one of: a position on the workpiece, a thickness of the workpiece at that position, and a separation distance between the second variable heat source and the workpiece.

  • Publication number: 20170043539
    Abstract: An automated in-line feed-through system and method, integrates the ability to control one or more variables during part fabrication with the layup of one or more fiber tows to form a composite part. The system includes an automated layup system configured to receive a feed-through of one or more fiber tows as an input material. The automated in-line feed-through system further includes a controller configured to respond to measurement data obtained by one or more samplings of the input material and/or a plurality of laid up plies that form a laminate. The controller in response to the obtained measurement data provides adjustment of the feed-through of the one or more fiber tows to compensate for a variation in one or more of the weights from a reference weight.

  • Patent number: 8591796
    Abstract: In accordance with one aspect of the present invention, methods for molding and curing of composite articles are provided. In one embodiment, the method includes providing a molding apparatus including an elastic layer disposed on a rigid support and a mold disposed on the elastic layer and the support. In one embodiment, the mold includes an inner surface, the inner surface further including a molding surface, and wherein a first surface of the elastic layer and the inner surface of the mold define a molding chamber. In one embodiment, a prepreg is further disposed within the molding chamber, wherein the prepreg is disposed on the first surface of the elastic layer. In one embodiment, the method includes providing a fluid via a fluid inlet against a second surface of the elastic layer, thereby expanding the elastic layer against the inner surface of the mold, and pushing the prepreg against the molding surface of the mold to form a molded composite article.
