  • Publication number: 20200290271
    Abstract: A fused filament deposition head is employed for depositing filament materials on workpieces to join the workpieces together. The workpieces can be of an automotive application, aerospace application, or something else. The fused filament deposition head, in an example, has a feed end, a dispensing end, and a heater. The feed end introduces more than one filament in the fused filament deposition head, as demanded in the larger application. The dispensing end delivers materials of the filaments to the underlying workpieces. The materials are delivered together. The heater serves to heat the filaments as they travel through the fused filament deposition head. The filaments can include a filament having a core portion of liquid-crystal polymer material.

  • Publication number: 20200290269
    Abstract: A composite fusion filament is disclosed that includes a polymer encasement and one or more mesogenic reinforcement bodies contained within the polymer encasement. The polymer encasement is comprised of a thermoplastic polymer, which has a melting temperature, and each of the one or more mesogenic reinforcement bodies is comprised of a thermotropic liquid crystal polymer, which has a clearing temperature. The melting temperature of the thermoplastic polymer included in the polymer encasement is less than the clearing temperature of the thermotropic liquid crystal polymer included in the one or more mesogenic reinforcement bodies. Additionally, the thermotropic liquid crystal polymer of each mesogenic reinforcement body has a plurality of organized crystalline fibrils that are aligned lengthwise along a longitudinal axis of the polymer encasement. A method of using the composite fusion filament to form a bond with a substrate that includes a thermoplastic polymer is also disclosed.

  • Publication number: 20200238637
    Abstract: Presented are manufacturing control systems for fabricating composite-material structures, methods for making/operating such systems, and resin transfer molding techniques for ameliorating race-tracking effects in fiber-reinforced polymer panels. A method for forming a composite-material construction includes confirming, via a system electronic control unit (ECU), that a fiber-based preform is placed in a mold cavity and that opposing mold segments of the molding apparatus are sealed together. A filler, such as a compressible bladder, a cluster of spring-biased pins, or a spray-chopped fiber bed, is introduced into a void between the fiber-based preform and a tool face of one mold segment to thereby eliminate an unwanted resin race track. The system ECU commands a resin pump to inject resin through a primary gate of the molding apparatus and into the mold cavity to thereby impregnate the fiber-based preform with the resin. One or more vents operate to evacuate air from the mold.

  • Patent number: 10592421
    Abstract: Instructions and logic provide advanced paging capabilities for secure enclave page caches. Embodiments include multiple hardware threads or processing cores, a cache to store secure data for a shared page address allocated to a secure enclave accessible by the hardware threads. A decode stage decodes a first instruction specifying said shared page address as an operand, and execution units mark an entry corresponding to an enclave page cache mapping for the shared page address to block creation of a new translation for either of said first or second hardware threads to access the shared page. A second instruction is decoded for execution, the second instruction specifying said secure enclave as an operand, and execution units record hardware threads currently accessing secure data in the enclave page cache corresponding to the secure enclave, and decrement the recorded number of hardware threads when any of the hardware threads exits the secure enclave.

  • Publication number: 20200061700
    Abstract: Systems and methods for additive manufacturing of a metallic component using a metal-powder paste are described. The metal-powder paste is a mixture including a non-uniform metal powder and a flowable additive. The metal-powder paste is applied to a surface of a substrate and spread to thereby produce a uniform-thickness layer in areas corresponding to the metallic component. The flowable additive is driven off using thermal energy to thereby form a layer of the non-uniform metal powder having a uniform thickness. The non-uniform metal powder is then fused to the substrate to thereby form the metallic component.

  • Publication number: 20190390379
    Abstract: Methods for forming composite articles include providing a non-crimp fabric (NCF) comprising a plurality of fiber plies maintained in a layup by stitching, wherein the stitching exhibits a lower structural tolerance to heat and/or UV light relative to the fiber plies, selectively degrading the stitching in one or more areas using heat or UV light, draping the NCF on a contoured article, applying a polymer matrix material to the draped NCF, and curing the polymer matrix material to form a contoured composite article. The stitching can be degraded in regions of the NCF which, when draped on the contoured article, correspond to topological features of the contoured article. Degrading the stitching can comprise breaking the stitching. The fiber plies can comprise carbon fibers, glass fibers, and/or basalt fibers. The contoured article can be tooling and/or an automotive component. The NCF can be a bi-axial NCF.
