  • Patent number: 6913821
    Abstract: Carbon composite components (1, 11, 22, 30), which may be aircraft brake discs, heat exchanger cores, and so on, are covered by protective coating 32. Component (1, 11, 22, 30) is immersed in liquid bath precursor of fluidized glass (step 55). After immersion step, glass-coated component (1, 11, 22, 30) is removed and annealed. Heat treatment gradually increases temperature to 250-350° C. at the rate of 1-2° C. per minute (step 60). Heat treatment is followed by soak at temperature of 250-350° C. for 1-10 hours (step 65). Temperature is then increased to 550-650° C. (step 70). Temperature is maintained at 550-650° C. for 1-10 hours (step 75). After completion of second prolonged heat treatment, the component is cooled until reaching room temperature (step 80). Upon completion of the annealing step, the fluidized glass coating converts to solid glass coating (32) enveloping and forming a protective barrier against undesirable oxidation of the C—C component (1, 11, 22, 30).

  • Patent number: 5972498
    Abstract: Solutions of intermediate molecular weight polymers from about 200,000 to about 4,000,000, such as polyethylene, in a relatively non-volatile solvent are extruded through an aperature at constant concentration and thereafter stretched at a ratio of at least about 3:1 prior to cooling to form a first gel. The first gels are extracted with a volatile solvent to form a second gel, and the second gel is dried to form a low porosity xerogel. Stretching occurs with any one or more of the first gel, second gel or xerogel. The polyethylene products produced by our process include products having a molecular weight between about 200,000 and about 4,000,000 a tenacity of at least about 13 grams/denier, a modulus of at least about 350 gram/denier, a porosity of less than 10% by volume, a crystalline orientation function of at least about 0.95, and a main melting temperature of at least about 140.degree.

  • Patent number: 5897952
    Abstract: Temperature adaptable fibers are provided in which a polyol/glyoxal based crosslinking system is used to create a water-insoluble polyacetal coating. The formaldehyde release properties characteristic of methylolamide finishing agents is avoided. The non-catalytic reaction utilizes stoichimetric amounts of sulfonic acids to derivatize the polyols which in turn react with the glyoxal to form a water-insoluble polymer. The material also possesses improved properties relating to soil release, durable press, resistance to static charge, abrasion resistance, pilling resistance and water absorbency.

  • Patent number: 5541238
    Abstract: Disclosed is a fiber of an organic, inorganic or metallic material or a simple substance wherein ultrafines of an inorganic or metallic material or a simple substance having an average particle diameter of 0.005-1 .mu.m are uniformly dispersed and deposited on 8-90% of the surface in a single layer. The fiber is produced by exposing a fiber of an organic, inorganic or metallic material or a simple substance to a gaseous stream forming ultrafines of an inorganic or metallic material or a simple substance by a vapor phase process, thereby contacting said ultrafines in the gaseous stream with said fiber in a state wherein the ultrafines are still active.
