Different temperature resistant glass fiber fabrics with a laminated aluminum layer on one side are analyzed regarding their ΔT behavior under convection heat transmission and radiant heat. The influences of material thickness as well as different exposure temperatures are investigated. The measured readings are compared by means of a controlled industrial air blower test set-up and two different measuring stations for heat radiation measurements (one according to SAE J2302). Road test data are used to derive a comparative statement on the potential practice-oriented suitability of the two different measuring methods during the engineering phase.
