  • Method and system for dynamic capillary-driven additive manufacturing of continuous fiber composite
    Patent number: 11897194
    Abstract: A process for additive manufacturing of a thermoset resin fiber reinforced composite comprises depositing a fiber material along a path having a direction; heating the fiber material using a heater to generate a moving thermal gradient in the fiber material trailing the heater relative to the path direction; and dispensing a thermosetting polymer material on the heated fiber material at a trailing distance the from the heater along the path. The thermosetting polymer dynamically wicks into the fiber material along the thermal gradient in the path direction.
    Type: Grant
