CHROMATIC WITNESS FOR THERMAL MAPPING AND CERTIFICATION OF HEAT BLANKETS

摘要

A method for heat blanket certification employs a thermochromatic coating containing one or more chromatic probes which is prepared and applied to a measurement surface. A test layup is created with the heat blanket (10) and a vacuum bagging film (18). The vacuum bagging film (18) is sealed and a vacuum is drawn through a vacuum probe in the vacuum bagging film (18). The heat blanket (10) is brought to operating temperature and the thermochromatic coating is illuminated with ultraviolet light. The chromatic probe coloration is then observed for determination of temperature consistency in the heat blanket (10).
