Engineering an Undergarment for Flash/Flame Protection
Abstract
This paper presents a continuation of projects spanning the last two years. In year one, the physical characteristics and medical effects of burns and Improvised Explosive Device, IED, blasts were investigated. In year two, the possible use of commercial intumescent materials with fabric was studied. The identified needs for research into the effect of undergarments on burn protection are focused in this study. Additionally, Thermal Protective Performance, TPP-(ISO 17492) and Air Permeability, AP-(ASTM D737) tests were performed to gather the data needed for the analysis of flame and thermal resistance as well as comfort and breathability. Out of the seven samples evaluated, the Sample D, composed of 94% m-aramid, 5 % p-aramid and 1% static dissipative fiber, shirt had the best overall performance in terms of air permeability, average TPP rating, and time to second degree burn. Another finding was that polyester undershirts may be dangerous in the event of a flash fire situation because the fabric could melt and stick to the Soldier's skin causing more severe burn injury. Additionally, an initial framework for a basic mathematical model representing the system was created. This model can be further refined to yield more accurate results and eventually be used to help predict the material properties required in fabrics to design a more protective undergarment.
