  • Extruding nozzle, system, and method therefor
    Patent number: 11517866
    Abstract: A method for pelletizing an extruded material with an extruding nozzle includes inserting the extruded material into the extruding nozzle so that the extruded material flows through at least one material-flow channel, extending through a radiator of the extruding nozzle. Heat is transferred between the extruded material, flowing through the at least one material-flow channel, and the radiator. At least a portion of the radiator is located within a housing of the extruding nozzle.
    Type: Grant
    Filed: March 4, 2021
    Date of Patent: December 6, 2022

  • Method for forming a composite structure
    Patent number: 11305859
    Abstract: A method for forming a composite structure includes the steps of: forming a fiber-reinforced polymer paste to a shape of a cavity of a dry fiber preform structure; heating said dry fiber preform structure having said fiber-reinforced polymer in said cavity to an infusion temperature; infusing resin into said dry fiber preform structure and around said fiber-reinforced polymer; and curing said resin-infused fiber preform structure and said fiber-reinforced polymer at a cure temperature higher than said infusion temperature.
