A fire retardant fabric is manufactured from oxidized polyacrylonitrile fibers having a fineness of about 0.5 to about 1.5 denier per fiber.

Fire retardant fabrics and methods for making the same

A process for making a high-strength spun yarn begins by feeding one or more tows of substantially uncrimped continuous filaments of high-modulus material having a tensile modulus exceeding about 20&#xd7;10psi through a high-speed stretch-breaking apparatus operating at low total draft ratio (preferably about 2.0) to break the filaments into high-modulus staple fibers having an average length in the range of about 5 to 6 inches. The tows advantageously are heavy, for example, having a denier of about 25,000 to about 500,000. Following the stretch-breaking step, the staple fibers are collected in sliver cans, and the staple fibers are advanced from the sliver cans to a spinning machine, where the fibers are spun into yarn. An important aspect of the invention is that no intermediate processes are performed between the stretch-breaking and spinning processes, which minimizes disruption of the alignment of and damage to the staple fibers.

A structural member for reinforcement of asphalt and concrete roadways and other products, and which comprises a gridwork of warp strands and weft strands which are disposed at right angles to each other and so as to define an open structure. In one embodiment, the gridwork is impregnated with a thermosettable B-stage resin so as to interlock the strands at their crossover points and maintain the gridwork in a semi-flexible state, and after being applied to the product to be reinforced, the resin is heated to convert the same into a fully cured composite to thereby rigidize the gridwork and reinforce the product. In cases where the product to be reinforced is heated, such as asphalt paving, the heat of the product provides the heat necessary to fully cure the resin in situ. In another embodiment, the resin is fully cured to rigidize the gridwork prior to its being applied to the structure to be reinforced. A method of producing the resin impregnated gridwork is also disclosed.

Method of reinforcing a concrete structure

A film having a width of at least about one foot as defined by the cross machine direction thereof and a substantially uniform average thickness of less than about 10 mils is formed of a crosslinkable thermoplastic olefin polymer, a crosslinking agent, and preferably a flame retardant. The film can be combined with a suitable substrate to form a prepreg or coated substrate, and the prepreg or coated substrate can be subsequently treated under conditions to crosslink the olefin polymer and to form a rigid composite structure. The composite structure is particularly useful for printed circuit board applications.
