A composite resin tank includes a wall joined to a dome along a joint. A softening strip is used to control stress in the joint.

A flame or heat flux protective coating composition, which includes a dispersion of fiberglass, hollow glass spheres, or a combination of both in silicone. A flame or heat flux protective sheet, which includes hollow glass spheres dispersed in silicone in a sheet form or fiberglass and silicone in a sheet form, wherein the fiberglass is dispersed in the silicone or the fiberglass is a woven cloth coated with the silicone is also presented. Articles incorporating the flame or heat flux protective coating or sheet form and methods for coating an article with the flame or heat flux protective coating composition are also presented.

A method of producing a flame resistant ticking includes laminating a flame resistant substrate to a decorative fabric, wherein the substrate is configured to release a chemical vapor that reduces the rate of propagation of a flame along the decorative fabric when the decorative fabric is exposed to flame. The substrate is laminated in direct contact with the inside surface of the decorative fabric. In some embodiments, the laminated ticking is configured to release less than 15 MJ of heat in the first ten minutes when exposed to a flame in accordance with the testing protocol set forth in 16 CFR 1633. Upholstered articles, such as mattresses, mattress foundations, and articles of furniture, may incorporate the flame resistant ticking layer.

A mattress, foundation, or other upholstered sleep product or article includes a core and barrier material surrounding the core. The barrier material includes flame and heat-resistant material that is configured to prevent combustion of the core when the upholstered article is impinged with a gas flame according to California Technical Bulletin 603 of the State of California Department of Consumer Affairs. The barrier material may include an intumescent material that is configured to swell and char in the presence of a flame so as to form a barrier to the flame and to heat generated by the flame.

Knit fabrics and military apparel such as T-shirts made therefrom are disclosed. The fabrics are constructed from blended yarns made from an intimate combination of nylon and cotton staple fibers. Such fabrics comprise a weight ratio of cotton to nylon which ranges from about 55:45 to about 85:15, and these fabrics also have a weight ranging from about 3 to about 8 oz/yd.sup.2. Knit fabrics of this type possess a desirable combination of good thermal protective properties, provided the specified high level of staple fiber blend uniformity is achieved, along with very useful abrasion resistance, bursting strength and drying time characteristics.

The invention relates to a flame-proofed polymeric composition suitable for coating workpieces, containing a vinyl acetate-containing thermoplastic polymer and an unsaturated elastomer containing double bonds as polymeric components, wherein the polymeric components are present in the form of a homogeneous polymeric mixture, and a mixture matrix vulcanized exclusively by a sulphur or sulphur-containing crosslinking system is formed, wherein the sulphur crosslinking system extends across the entire matrix and permeates the matrix completely, andat least one flame retardant or a combination of flame retardants. The invention further relates to articles produced therefrom, and to composite elements coated with this composition and to a method for producing the same.

A fabric or belt and a method for forming such a fabric or belt, including a base support structure and at least one coating with the coating being applied by a thermal spray process.

A laminated sheet includes a base cloth layer having a porous structure obtained by impregnating a woven fabric, which has a tear strength by a trapezoid method of 150 N or more in the longitudinal direction and 100 N or more in the lateral direction, with a resin composition containing a polyurethane resin and an organic flame retardant, and a skin layer layered on the base cloth layer, and has plural air holes penetrating in the thickness direction.

Insulation materials have a coating of a partially cured polymer on a plurality of fibers, and the plurality of coated fibers in a cross-linked polymeric matrix. Insulation may be formed by applying a preceramic polymer to a plurality of fibers, heating the preceramic polymer to form a partially cured polymer over at least portions of the plurality of fibers, disposing the plurality of fibers in a polymeric material, and curing the polymeric material. A rocket motor may be formed by disposing a plurality of coated fibers in an insulation precursor, curing the insulation precursor to form an insulation material without sintering the partially cured polymer, and providing an energetic material over the polymeric material. An article includes an insulation material over at least one surface.

Disclosed are technical fibers and yarns made with partially aromatic polyamides and a fiber having vapor phase action such as an FR cellulosic fiber. Fabrics made from such fibers and yarns demonstrate superior flame retardancy over traditional flame retardant nylon 6,6 fabrics. Further, the disclosed fibers and yarns, when blended with other flame retardant fibers, do not demonstrate the dangerous scaffolding effect common with flame retardant nylon 6,6 blended fabrics.
