摘要： A composite flame barrier includes at least two layers of nonwoven flame resistant fibers, and at least one active chemical layer including a heat absorbing intumescent or endothermic compound, the active chemical layer being mechanically bound to and at least partially embedded within the nonwoven fiber layers. The composite flame barrier is particularly useful in applications that require a flexible, extended time fire barrier. Such applications include, for example, fuel line, process pipeline and valve protection when transporting combustible liquids; structural steel fireproofing, electrical cable wrap and fire-rated wall assemblies, especially those requiring two, three and four hour fire-ratings, when tested according to ASTM E-119 or similar testing methods and standards.
摘要翻译：复合火焰阻挡层包括至少两层非织造阻燃纤维，以及至少一个活性化学层，包括吸热膨胀型或吸热性化合物，活性化学层被机械地结合并且至少部分地嵌入在非织造纤维层内。复合火焰屏障在需要灵活，延长的时间防火屏障的应用中特别有用。这样的应用包括例如运输可燃液体时的燃油管线，过程管道和阀门保护; 结构钢防火，电缆包装和防火墙壁组件，特别是那些需要两个，三个和四个小时的防火等级，根据ASTM E-119或类似的测试方法和标准进行测试时。

摘要： A composite flame barrier includes a woven or nonwoven fiber sheet material including flame resistant fibers of oxidized polyacrylonitrile; a mineral hydrate material at least partially embedded within the fiber sheet material. The fiber sheet material may be covered on one or two sides with an outer laminar material. The composite flame barrier is particularly useful in fire-rated wall assemblies, especially those designed to provide two, three and four hour fire-ratings, when tested according to ASTM E-119 or similar testing methods and standards.

摘要： A method of making a sized and resin-coated fiber tow for use in a fiber reinforced composite. the method comprising the steps of providing a fiber, contacting at least a portion of the fiber with a sizing slurry to form a sized and resin-coated fiber, the sizing slurry comprising 0.1-25% by weight of a sizing agent and 20-80% by weight of a matrix-resin powder in a solvent, based on the total weight of the sizing slurry. wherein the total solid content, including the sizing agent and the matrix-resin powder, of the sizing slurry is greater than 30 wt. %. The method further comprising drying the sized and resin-coated fiber at a temperature below the melting point of the matrix-resin powder, thereby forming a dried sized and resin-coated fiber and winding the dried sized and resin-coated fiber onto a spool.
