    Abstract: A method for fabricating a perforated high temperature fiber reinforced polymer composite material which includes partially curing a polymer composite material to a viscoelastic state without inducing complete cure. The polymer composite material is formable when further heated, but does not experience excessive resin flow during final curing. According to the methods of the present invention, the polymer composite material may be perforated in the partially cured state, or prior to the partially cured state. A rigid pin mat apparatus of the present invention may advantageously be utilized to perforate the composite material. After the partial curing, the polymer composite material may be contoured utilizing a flexible mat pin apparatus of the present invention, or may be contoured utilizing forming tools generally known to the art. The method may advantageously be utilized with fiber-reinforced polymer composite starting materials, such as graphite/bismaleimide preimpregnated fabric, to produce perforated and contoured high temperature fiber reinforced polymer composite materials for sound suppression applications.

    Abstract: An optical power limiter and switch, transparent at low light intensity and opaque at high intensity, is comprised of a pair of right triangular prisms (10, 12) separated by a liquid film (32) whose refractive index changes in response to optical energy. A first or input lens (34) focuses the light (36) upon the liquid film at an angle (i) less than the critical angle of total reflection of the prism-liquid interface and a second or output lens (40) refocuses the energy to a detector through an aperture. When the intensity of the optical energy reaches a first predetermined level, the optical energy is defocused and diverted from the detector. When the intensity of the optical energy reaches a second predetermined higher level, the critical angle is achieved whereupon the optical energy is reflected away from the interface rather than through it. The liquid material of the film also includes an optically absorbent dye for attenuating optical energy of predetermined wavelengths transmitted through the film prior to defocusing and total reflection.

    Abstract: This invention relates to a process for making composite materials involving the in situ precipitation of second phase particles in a metal matrix, and the products thereof. The process involves the use of initial compound materials as a source of second phase-forming reactants in the production of metal-second phase composites. The composites produced may comprise distributions of either single or multiple second phase materials. Exemplary initial compound precursors include boron nitride, boron carbide, boron oxide, aluminum nitride, aluminum carbide, aluminum boride, iron oxide and copper oxide.

    Abstract: A method for the introduction of in-situ precipitated second phase materials, such as ceramic or intermetallic particles in a metal matrix, to a host metal. When an initial solvent-assisted reaction is utilized, metal-second phase composites having highly superior properties may be obtained. The invention may utilize the reaction of the second phase-forming constituents in a solvent metal medium to provide an intermediate material of finely-dispersed second phase particles in an intermediate metal matrix, in the form of a porous mass or sponge. Any desired loading of second phase in the final composite may be achieved by the admixture of this preformed intermediate material having a relatively high content of particulate material, with a molten host metal. Exemplary materials include titanium diboride in an aluminum matrix and titanium carbide in an aluminum matrix.

    Abstract: A high force-gain valve (10) including a housing (12) having first (14) and second openings (16) therein, a fluid diverter (24) fixed in position within the housing and aligned with the second opening, a translatable gate (28) closely surrounding the diverter and having a sealing edge (30) which in the closed position seats against the portion of the housing adjacent the second opening, and a positioner for translating the gate between open and closed positions. The gate is hollow, its interior being in fluid communication with the interior of the housing, and has a beveled sealing edge, exposing most of the sealing edge to the fluid pressure within the housing, and is therefore force balanced. The force balancing permits the gate to be easily and quickly translated and positioned between the open and closed positions.
