  • Apparatus for co-curing composite skins and stiffeners in an autoclave
    Patent number: 9738039
    Abstract: A composite skin and composite stiffeners are co-cured in an autoclave. Uncured stiffeners are placed in channels of a tool, and an uncured skin is placed on the tool contacting the stiffeners. The vacuum bag is sealed over the tool. Bladders placed in the stiffeners are exposed to autoclave pressure through a manifold system employing vent tubes that pass through the vacuum bag along a side of the tool.
    Type: Grant

  • Temporary clamp up system for sealant squeeze out in lock bolt installations
    Patent number: 9644659
    Abstract: A joint fastening system employs a lock bolt having a pull stem and locking threads inserted through a bore in a joint having fay sealant between layers. A collar is received over the pull stem to engage the threads, the collar producing tension on the threads to generate clamp force sufficient for fay sealant squeeze out.

  • Iron-based amorphous alloys and methods of synthesizing iron-based amorphous alloys
    Patent number: 9328404
    Abstract: A method according to one embodiment includes combining an amorphous iron-based alloy and at least one metal selected from a group consisting of molybdenum, chromium, tungsten, boron, gadolinium, nickel phosphorous, yttrium, and alloys thereof to form a mixture, wherein the at least one metal is present in the mixture from about 5 atomic percent (at %) to about 55 at %; and ball milling the mixture at least until an amorphous alloy of the iron-based alloy and the at least one metal is formed. Several amorphous iron-based metal alloys are also presented, including corrosion-resistant amorphous iron-based metal alloys and radiation-shielding amorphous iron-based metal alloys.
