Abstract:
Fibrous structures of high complexity, as introduced by ply and twist, have been subjected to high and low speed tensile tests. The ratio of strength at high speed to low speed is always greater than one, but decreases with increasing complexity of fibrous structure. The ratio of elongation to break at high speed to that at low speed is always less than one and also decreases with increasing structure complexity. The ability to absorb energy markedly increases with increasing complexity of geometry at low strain rates, characteristic of an Instron. The reasons for this additional energy absorption are discussed. Tests at high rates of strain 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.
