MEASUREMENT AND FORECASTING OF MATERIALS SAMPLES’ TEMPERATURE DURING WEATHERING IN DIFFERENT CLIMATIC ZONES
The relation between standard meteorological parameters and surface temperature of samples exposed directly to the sun and in a sheltered environment has been studied using 6–8-year timeframe. The following materials have been used: KMKU-3.150.U0.1 carbon fiber reinforced polymer, KMKS-4.175.Т10 glass fiber reinforced polymer, and D16-AT aluminum alloy substrate with black and white EP-140 epoxy coating . Outdoor weathering has been conducted at Gelendzhik and Moscow testing sites of the All-Russian Institute of Aviation Materials (VIAM). It has been shown that it′s possible to use a multilinear model to estimate the temperature of the materials′ surfaces during their weathering in different climatic regions. The following parameters for 1–12 months’ timeline have been used to estimate samples’ temperature at different locations: air temperature, total solar radiation, solar declination, and solar hour angle.
