- Abstract
- A 1200 watt CO(2) laser has been used to test the vulnerability of cloths of natural and synthetic fibers that are used for making army clothing, equipage, and tentage items. The ignition behavior is shown for a range of irradiance levels and exposure times (continuous and pulsed irradiation), to 80 w/cm2, single pulse to 10 seconds, pulse frequencies of 5,50 and 100 pulses per second, and pulse widths of 100, 10, and 5 milliseconds. the physical effects of glowing, charring, melting and flaming are discussed.
