Patent number: 7595112Abstract: A method of fabricating a metal/composite hybrid laminate is provided. One or more layered arrangements are stacked on a solid base to form a layered structure. Each layered arrangement is defined by a fibrous material and a perforated metal sheet. A resin in its liquid state is introduced along a portion of the layered structure while a differential pressure is applied across the laminate structure until the resin permeates the fibrous material of each layered arrangement and fills perforations in each perforated metal sheet. The resin is cured thereby yielding a metal/composite hybrid laminate.Type: GrantFiled: July 31, 2006Date of Patent: September 29, 2009Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Roberto J. Cano, Brian W. Grimsley, Erik S. Weiser, Brian J. Jensen

Patent number: 7541388Abstract: A fully imidized, solvent-free polyimide foam having excellent mechanical, acoustic, thermal, and flame resistant properties is produced. A first solution is provided, which includes one or more aromatic dianhydrides or derivatives of aromatic dianhydrides, and may include one or more aromatic diamines, dissolved in one or more polar solvents, along with an effective amount of one or more blowing agents. This first solution may also advantageously include effective amounts respectively of one or mores catalysts, one or more surfactants, and one or more fire retardants. A second solution is also provided which includes one or more isocyanates. The first and second solutions are rapidly and thoroughly mixed to produce an admixture, which is allowed to foam—in an open container, or in a closed mold—under ambient conditions to completion produce a foamed product. This foamed product is then cured by high frequency electromagnetic radiation, thermal energy, or a combination thereof.Type: GrantFiled: May 5, 2005Date of Patent: June 2, 2009Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Juan M.

Publication number: 20080286473Abstract: Hydrophobic coating compositions containing siloxanes and fluoropolymer resin hinder the accumulation of moisture and reduce the adhesion of ice formed on the coating. Applications of such coating compositions to surfaces thus reduce the propensity for ice formation on a treated surface, and ease the dislodging of any ice formed on the treated surface.Type: ApplicationFiled: May 18, 2007Publication date: November 20, 2008Applicants: and space Ad+Inventors: Trent M. Smith, Erik S. Weiser, Roberto J. Cano, Michael E. Prince, Leslie A. Curtis, Charles D. DeWeese

Publication number: 20080272232Abstract: A jet engine exhaust nozzle flow effector is a chevron formed with a radius of curvature with surfaces of the flow effector being defined and opposing one another. At least one shape memory alloy (SMA) member is embedded in the chevron closer to one of the chevron's opposing surfaces and substantially spanning from at least a portion of the chevron's root to the chevron's tip.Type: ApplicationFiled: June 14, 2007Publication date: November 6, 2008Applicant: Administrator of the National Aeronautics and and Space AdministrationInventors: Christopher M.

Patent number: 6514370Abstract: An apparatus for producing a hybrid boron reinforced polymer matrix composite from precursor tape and a linear array of boron fibers. The boron fibers are applied onto the precursor tapes and the precursor tape processed within a processing component having an impregnation bar assembly. After passing through variable-dimension forming nip-rollers, the precursor tape with the boron fibers becomes a hybrid boron reinforced polymer matrix composite. A driving mechanism is used to pulled the precursor tape through the method and a take-up spool is used to collect the formed hybrid boron reinforced polymer matrix composite.Type: GrantFiled: June 8, 2000Date of Patent: February 4, 2003Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Harry L Belvin, Roberto J.

Patent number: 6500370Abstract: The invention is an apparatus and method for producing a hybrid boron reinforced polymer matrix composition from powder pre-impregnated fiber tow bundles and a linear array of boron fibers. The boron fibers are applied onto the powder pre-impregnated fiber tow bundles and then are processed within a processing component having an impregnation bar assembly. After passing through variable-dimension forming nip-rollers, the powder pre-impregnated fiber tow bundles with the boron fibers become a hybrid boron reinforced polymer matrix composite tape. A driving mechanism pulls the powder pre-impregnated fiber tow bundles with boron fibers through the processing line of the apparatus and a take-up spool collects the formed hybrid boron-fiber reinforced polymer matrix composite tape.Type: GrantFiled: July 18, 2000Date of Patent: December 31, 2002Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Harry L.

Patent number: 6222007Abstract: High quality films, preimpregnated tape (prepegs) and composites have been fabricated from polyimide precursor “salt-like” solutions. These “salt-like” solutions have a low viscosity (5,000 to 10,000 cp) and a high solids content (50-65% by weight) and can be coated onto reinforcing fiber to produce prepegs with excellent tack and drape at 12-15% residual solvent (˜4-6% water from thermal imidization reaction). The processing of these types of prepegs significantly overcomes solvent removal problems and allows excellent fiber wet out. In addition, the physical characteristics of the polyimide precursor “salt-like” solutions permits processing into high-performance materials through the use of standard prepregging and composite fabrication equipment. The resultant composites are of high quality.Type: GrantFiled: May 29, 1998Date of Patent: April 24, 2001Assignee: The United States of America as represented by the National Aeronautics and Space AdministrationInventors: Roberto J.
