Flexible Fibrous Structural Materials.

摘要

The objective of this program is the development and evaluation of fibrous structural materials exhibiting good flexibility and high strength at temperatures from cryogenic to 2000 F. The weight, permeability, flexural rigidity, wrinkle recovery, tensile properties, tear strength, and fold endurance at 70 F of a fabric woven from a multifilament yarn composed of 0.0005-inch-diameter nickel-chromium alloy wire are given. The high-speed impact properties of a metal yarn, an HT-1 yarn and an HT-1 yarn wrapped with metal yarn are also given. A preliminary investigation of the joining of panels of metal fabric by sewing is discussed. The properties of coreless cord braided from halfmil and one mil wire are given. Metal yarns textured by the various textile texturing processes are evaluated. A preliminary investigation of metal filaments blended with other fibers is discussed. The tensile properties at temperatures from 70 F of a series of graphite and carbon-based fabrics are given. (Author)
