Publication number: 20040092189Abstract: The invention relates to a method for producing a composite from inorganic substances and binders on the basis of silane. The inventive method is characterized by the use of one or more silicon compounds of the general formula (1) as the binder, wherein R represents groups that are the same or different and that cannot be hydrolytically cleaved, and wherein X represents one or more hydroxyl groups or one or more hydrolytically cleavable groups that are the same or different, and n is a number between 0 and 3, preferably between 1 and 2. Said silicon compounds have been previously condensed with understoichiometric amounts of water per mole silicon compound in the presence of alkaline or acidic catalysts. The inorganic substances used are bundles or strands of glass and/or mineral fibers onto which the precondensed silicon compounds have been sprayed in amounts of from 1 to 20% by weight, preferably together with overstoichiometric amounts of water.Type: ApplicationFiled: July 1, 2003Publication date: May 13, 2004Inventor: Roman Rupp

Patent number: 6451715Abstract: Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.Type: GrantFiled: January 22, 2001Date of Patent: September 17, 2002Assignee: Milliken & CompanyInventors: Shulong Li, John A.

Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessarily low permeability levels. Thus, the inventive coated inflatable airbag comprises a film laminated on at least a portion of the target fabric surface wherein the film possesses a tensile strength of at least 2,000 and an elongation at break of at least 180%.Type: GrantFiled: January 22, 2001Date of Patent: August 6, 2002Assignee: Milliken & CompanyInventors: Shulong Li, John A.

Patent number: 5902756Abstract: The present invention is a fiber reinforced ceramic matrix composite substrate with an integrated ceramic topcoat layer. The composite substrate is prepared by laminating a preceramic polymer impregnated fiber cloth, curing the laminate, and pyrolyzing the resulting substrate to an initial state. The composite substrate is re-infiltrated with the preceramic polymer, cured, and pyrolyzed to an initial densification level. The topcoat layer is then integrated with the composite substrate by applying transition plies to an exterior surface of the composite substrate, forming a particulate slurry from a ceramic powder and the preceramic resin, and applying the particulate slurry to the transition plies. The transition plies-particulate slurry layup on the composite substrate is autoclave cured and pyrolyzed. The composite substrate is then re-impregnated with the preceramic resin matrix material, cureclave cured, and step pyrolyzed to a desired densification level.Type: GrantFiled: July 25, 1996Date of Patent: May 11, 1999Assignee: Northrop Grumman CorporationInventors: Elsid I.
