WebThe emissivity coefficient - ε - indicates the radiation of heat from a 'grey body' according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal 'black body' with the emissivity coefficient ε = 1. The emissivity coefficient - ε - for some common materials can be found in the table below. Note that the emissivity coefficients for … WebThe materials of face sheets and the CFC are respectively the glass fiber reinforced plastic (GFRP) and the carbon fiber reinforced plastic (CFRP), both of that are orthotropic.
