Physico-Chemical Behavior and Thermo-Optical and Mechanical Properties of Glassy Carbon Up to 2100 K Under Low-Energy Proton and Vacuum Ultraviolet Irradiations

In the frame of mission for Sun approach, to understand effects heating solar corona and acceleration winds, research was carried out study behavior glassy carbon that can be used heat shield. The physicochemical from 1600 up 2100 K with or without proton bombardment VUV irradiation studied together measurement thermal optical properties, ratio absorptivity total hemispherical emissivity conditioning equilibrium Experimental results obtained on massive samples are presented through mass spectrometry, loss rate microstructural characterization (XRD, SEM…), mechanical thermo-optical properties. Finally, synergistic effect high temperature, protons radiation has a low impact this material.
