  • Publication number: 20220324310
    Abstract: The present disclosure provides a composite lift gate for a vehicle. The composite lift gate includes a polymer matrix and a fiber assembly. The fiber assembly is embedded in the polymer matrix. The fiber assembly includes a fiber mat and a plurality of substantially-aligned continuous fibers. The plurality of substantially-aligned continuous fibers is directly connected to a portion of the fiber mat. In one aspect, the composite lift gate further includes an electronic component connected to the fiber assembly. In various aspects, the present disclosure provides a method of manufacturing a composite lift gate for a vehicle.

  • Publication number: 20220134607
    Abstract: A method of fabricating a preform is provided. The method includes disposing a veil over a first mold portion having a three-dimensional shape, the veil including a thermoplastic material and magnetic particles; disposing a fiber tow onto the veil; heating at least a portion of the veil by induction so that the fiber tow becomes coupled to the veil; compressing the fiber tow and the veil toward each other with a second mold portion that has a negative contour relative to the first mold portion; and removing the preform from the first and second mold portions. The preform has the three-dimensional shape and includes the fiber tow coupled to the veil. Preforms prepared by the method are also provided.

  • Patent number: 10558802
    Abstract: Systems and methods for actively securing data storage devices utilize the technique of storage virtualization. In embodiments, would-be cyberattackers are presented with many possible “ports” or “channels” by which to communicate over a network with a data storage device. Unknown to the attacker, at any given time, only one of these ports or channels is the “correct,” or “active,” port; all of the other ports are dummies that do not permit communication with the storage device. The active port is dynamically, randomly, and/or continually reconfigured, seriously impeding the ability of the attacker to access the data storage device through the active port.
