| This investigation focused on the experimental evaluation of transient heat transfer through thin fibrous layers. The study utilized a vertical heated air jet impinging on a flat surface with uncontrolled temperature made of skin simulant. Efforts were directed to understanding heat transfer as a function of time and location. It was found that the heat transfer profile across the plate depended on nozzle-to-plate separation. In addition, the performance of three commonly used fire resistant/flame retardant fabrics was analyzed. Fabrics were tested in contact and 6mm away from the plate. In all cases, NomexRTM IIIA consistently allowed higher rates of heat transfer. InduraRTM and KevlarRTM/PBI performed comparably during contact testing, but varied significantly as they were located away from the skin simulant. |
