  • Honeycomb core stabilization for composite parts
    Patent number: 12515436
    Abstract: Processes for fabricating a partially stabilized honeycomb core is disclosed where a stabilizing layer of an adhesive film is aligned with and adhered to only one exterior surface of a honeycomb sheet. The opposed exterior surface thereby remains uncovered. A preform of the partially stabilized honeycomb core may be subjected to ambient atmospheric pressure cure conditions at an elevated temperature sufficient to adhere the stabilizing layer to the one exterior surface of the honeycomb sheet and thereby provide a partially stabilized honeycomb core that is partially stabilized against compressive forces exerted in widthwise and lengthwise directions thereof yet allows bending of the partially stabilized honeycomb core about axes in the widthwise and lengthwise directions.
    Type: Grant
