Improving the heat, fire, and melt resistance of elastomeric seals on military gas masks

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering, 2009.Cataloged from PDF version of thesis.Includes bibliographical references (p. 62-63).Improvised Explosive Devices (IED's) have wreaked havoc amongst American and Coalition troops. They have been the number one killer of Coalition forces. Many times the impact knock out fuel tanks which then catch on fire, causing life threatening burn injuries. As a counter, the military unveiled new fire/melt resistant clothing. In the case of a chemically contaminated environment, the soldier will have to rely on a gas mask with an elastomeric seal that is not resistant to fire or melting. If a soldier is traveling in a vehicle with his or her gas mask on and gets hit by an IED, facial and eye bum injuries are very possible. New material must be found that can help prevent these injuries, particularly concerning the seal. The goal is to find the best combination of a suitable elastomer, curing agent, and filler that can give the soldier precious time to escape a burning vehicle. Various types of materials are discussed concerning thermal, other physical properties, cost, and relevant patents.by Charles S. Hong.M.Eng
