  • Composite aircraft floor system
    Patent number: 8709584
    Abstract: An aircraft floor system includes a composite panel which generally includes an inboard layer, an inboard interlock layer, a core layer, an outboard interlock layer and an outboard layer. The advanced sandwich core material may include K-Cor™ or X-Cor™ which is pinned through at least one ply of dry composite reinforcement to provide a mechanical lock between the pins and an inboard and outboard interlock layer. Bonding of the locked-in ply with the inboard and outboard results in improved structural performance and damage tolerance.
    Type: Grant
    Filed: January 26, 2007
    Date of Patent: April 29, 2014
    Assignee: Sikorsky Aircraft Corporation
    Inventors: Thomas A. Carstensen, David M. Cournoyer, Dan Ursenbach
  • Composite core densification
    Patent number: 8673418
    Abstract: A reinforcement tube includes at least one composite ply material strip in a coil configuration. The coil configuration defines a tube rectilinear in cross-section and a helical opening.

  • High pressure co-cure of lightweight core composite article utilizing a core having a plurality of protruding pins
    Patent number: 6739861
    Abstract: The composite molding apparatus includes a rigid base member and a complementary semi-rigid mold member or “black bag” caul plate having a sieve member formed therein. The sieve member layer of the semi-rigid mold member engages pins which extend from the sandwich core to limit penetration into the semi-rigid mold member to a predetermined depth. The semi-rigid mold member is supported relative to the rigid mold member by the pins to provide uniform pressure transfer to the composite article during a high pressure co-cure molding process without crushing the sandwich core.
