- Abstract
- The use of gas chromatography/infrared spectroscopy to correlate the spectrum of combustion products produced by smoldering samples with the electrical response of polymeric early-warning fire detection and to make improvements in device design and performance was studied. The most significant success was in the device ara, in which successful fabrication of charge-flow transistor structures, made possible a realistic, low-cost, miniaturized sensor design. The documentation of polymer responses to a variety of smoldering sources, including cellulose, acrylic, urethane, polyvinyl chloride and wood, was improved.
