Thermal Effectiveness of Multilayer Heat Shielding Automotive Components - Influences of Different Layers on Heat Radiant and Convection Heat Measurements 2015-01-1713

Different heat shielding unilayer materials already in practical use and multilayer materials, consisting of a compound of E-glass fabric laminated with aluminum foil and different high temperature felts, are compared with regards to the difference between the external and internal surface temperature ΔT as a function of the external surface temperature. Beside that the general difference between the two standard methods convection heat measurement and radiant heat measurement is shown. Especially it is evaluated whether the radiant heat measurement method is suitable to make a general statement for classification of heat shielding materials.
