  • Patent number: 6533977
    Abstract: A high temperature, composite structure includes a blank of wire mesh material fabricated from drawn wire from a stainless steel rod. The drawn wire is annealed and mixed to create raw material. The mixed raw material is knitted to create the blank of wire mesh material, the blank of wire mesh material having voids formed therein. A dispersion comprising vermiculite as a binder is impregnated within the blank of wire mesh material. The dispersion substantially fills the voids of the blank of wire mesh material. A method of manufacturing the structure is further disclosed. Specifically, the method includes the steps of providing a blank of wire mesh material having voids formed therein, impregnating the blank of wire mesh material with a dispersion consisting of vermiculite, the dispersion substantially filling the voids, eliminating a water fraction of the dispersion, and pressing the impregnated blank of wire mesh material to a desired shape and density.

  • Patent number: 6309987
    Abstract: A nonwoven fabric with UV stability and flame retardancy having at least one fabric layer. The fabric layer is made of a base resin, preferably polyolefinic, and a non-halogenated melt processable compound that is selected from the group consisting of N-alkyoxy amines and are combined into a homogeneous blend which is then either spunbonded or meltblown to form the fabric layer. A melt processable fluorochemical additive may also be combined into the homogeneous blend to provide liquid barrier properties to the fabric layer.

  • Patent number: 5972434
    Abstract: Fire resistant glass fiber products are produced by coating the glass fibers with at least one nitrogen containing compound and at least 10 weight percent of at least one boron containing compound, drying the glass fibers and curing a binder that is in the coating. The nitrogen containing compound(s) are present in sufficient amounts that there is at least one mol or atom of nitrogen present for each mol or atom of boron present in the boron containing compound(s). When the product is exposed to a fire or high temperatures, such as about 1000 degrees F. or higher, the nitrogen released from the nitrogen containing compound(s) reacts with boron or boron oxide to form a sheath of refractory material around the fibers that protects the fibers and allows the fibers to maintain integrity to higher temperatures and/or for longer times than untreated fibers.
