The Mechanical Properties of Textile Materials as Influenced by Structure and Strain Rate

Abstract

Fibrous structures of increasing complexity, as introduced by ply and twist, were subjected to high and low speed tensile tests. The ratio of the strength at high speed to that at low speed is always greater than one but decreases with increasing complexity. The ratio of the elongation to break at high speed to that at low speed is always less than one and also decreases with increasing complexity of structure. The ability to absorb energy markedly increases with increasing complexity of geometry at the low strain rates characteristic of the Instron. The reasons for this additional energy absorption are discussed. Tests at high rates of straining point out the inability of many complex textile structures to translate their superior energy absorption characteristics to high strain rates. The results obtained and the principles demonstrated are applied to the development of improved materials for use in aerial delivery and ballistic applications.
