  • Processes for repairing complex laminating composites
    Patent number: 10850460
    Abstract: Complex laminated composites may be repaired by removal of individual damaged plies through peeling in order to exploit the weaker interlaminar properties of these composites. Upon removal of the individual damaged plies through peeling, replacement plies may be added to restore the laminated composite. In addition, when damage extends through the thickness of a laminated composite, a plug may be used to allow plies to be replaced while maintaining contour within the repair region. A caul plate also may be used to stiffen and maintain the contour of a repair region while peeling and removing plies from the repair region.
    Type: Grant
    Filed: November 25, 2019
    Date of Patent: December 1, 2020

  • Vacuum assisted conformal shape setting device
    Patent number: 9930728
    Abstract: A device and method for applying treatment to a structure includes a housing having a first membrane sealed to a second membrane for creating an airtight cavity therebetween for receiving a porous material and a working layer. The method includes the process of conforming the shape of the housing to the structure and applying a treatment thereafter to the structure.
