Temperature of the internal surfaces of composite nonwoven samples versus exposure time of their external surfaces to thermal radiation with a flux density of 3 kW/m2
Sample 1 – composite nonwoven sample; thermal radiation fell on the white foil
Sample 2 – composite nonwoven sample; thermal radiation fell on the black foil
With PES-Al. Foil – Sample 2 + aluminized PES foil; thermal radiation fell on the PES foil
