Abstract: An architectural wall panel comprising a panel body including a generally rectangular face plate having an upper end and a lower end. An upper flange generally extends in a rearward direction the upper end and includes a first projection projecting laterally relative to the rearward direction. A lower flange generally extends in a rearward direction from the lower end of the face plate and terminates in a clip. The clip includes a first portion extending toward the upper flange and a second portion extending away from the upper flange and is configured to clamp therebetween a first projection of a second architectural wall panel positioned below the architectural wall panel.

Abstract: A syntactic foam composition is formed from a resin binder containing microspheres and minispheres and having a thermal conductivity less than 0.120 watts/meter° K.

Abstract: A double hull marine vessel is provided which includes a syntactic foam-macrosphere composition between the inner and outer hulls which dissipates force applied to an outer hull.

Abstract: A method for producing flexible, low-bulk towpreg which involves powder coating a bundle of unspread fiber tows arranged in a predetermined cross-sectional shape, and the resulting towpreg. During the powder coating process, the resin powder particles do not enter into the fiber bundle, but rather only coat the surface fibers comprising the tows, resulting in dry fibers in the core of the towpreg and outer fibers which are coated with a discontinuous sheath of resin on the surface of the towpreg surrounding the core of dry fibers. The resin layer on the surface of the towpreg is formed by a partial melting of the powder particles. A post treatment process can be used to convert flat ribbon towpreg produced in accordance with the present invention into flexible unidirectional tape.

Abstract: A clamp for a cylindrical object is provided which is formed of fibers in the form of woven fabric molded in a polymeric matrix. The clamps have two free ends through which one or two rods extend. The compressive force exerted by the clamp can be adjusted by adjusting the distance between the free end.

Abstract: The invention provides a ceramic composite material which includes 50-90% boron carbide, 5-30% silicon carbide, and 3-22% titanium carbide. All constituents are in powder form, and have a particle size of between 1 and 40 microns, and a purity of at least 97%. The powdered constituents are blended and consolidated by either hot isostatic pressing (HIPing) or by hot pressing, although blanks of less quality can be formed by mere sintering.

Abstract: The invention provides a ceramic composite material which includes 60-85% silicon carbide, 4-15% titanium carbide, 4-20% titanium boride, 4-13% aluminum oxide, and 1-8% titanium oxide. All constituents are in powder form, and have a particle size of between 1 and 40 microns, and a purity of at least 97%. The powdered constituents are blended and consolidated by sintering, although either hot isostatic pressing (HIPing) or by hot pressing can be used to improve certain properties such as impact resistance.

Abstract: A double hull marine vessel is provided which includes a syntactic foam-macrosphere composition between the inner and outer hulls which dissipates force applied to an outer hull.
