  • Foldable explosive threat mitigation unit
    Patent number: 11307012
    Abstract: An explosive threat mitigation unit (TMU) stands ready to receive a suspected bomb, enclose it, and contain the explosion if one occurs. An operator protects bystanders and surroundings by putting the suspected bomb in a TMU and then closing the TMU. If the bomb goes off, the TMU mitigates the effects of both the blast and the fragments. One variation has a container, a tube, a cap, and a door. The container includes an opening. The tube, arranged in the container, aligns with the opening. The cap slides through the opening and over the tube. The door slides into place to close the opening and enclose the cap within the container.

  • Composite structure and method of making a composite structure
    Patent number: 9273933
    Abstract: In accordance with the present teachings, a method of producing composite having a 3A Q3D reinforcement phase is disclosed. The method of producing the composite provides producing a three-dimensionally woven configuration where a first fiber from a first sheet of reinforcement phase is interwoven or mechanically linked with at least one of an adjacent second layer and then back into the first sheet. The linking fibers are passed between layers at an acute angle generally less than about 10 degrees. The method includes impregnating the woven construction with a curable polymer such as epoxy.
