  • Shape memory alloy member for use in polymer or composite seal applications
    Patent number: 10612658
    Abstract: A sealing system (100) that includes a first component (112), a second component (114) and a polymer seal (116) positioned in a seal recess (118) in the first component. A TWSMA member (122) is positioned in the seal recess (118), wherein the TWSMA member (122) has a retracted shape (122R) and an expanded shape (122E), the TWSMA member (122) transitioning from the retracted shape (122R) to the expanded shape (122E) at a temperature that is less than an installation temperature when the polymer seal (116) and the TWSMA member (122) were positioned in the seal recess (118).
