The heating curves for a number of different materials, including metals and non-metals, were observed while being irradiated with a beam from a C02 gas laser. The radiant energy spectrum emitted by the materials was measured and recorded, and from this data the heating and cooling rates of the materials were determined. Infrared measurements in the 3 to 5 micron and 8 to 14 micron regions were performed using two Barnes Spectral-Master Radiometers. Data was recorded with both stationary and moving target materials to determine the effect of airflow on the heating and cooling characteristics of the materials. The observed initial heating curve for the solid materials up to the melting point are compared with a theoretical model. The procedure for calibration of the equipment and for data collection is also contained in this thesis.These measurements are important because the experimental conditions closely approximate realistic environmental conditions for materials which are used in different types of aircraft during flight.
