The char density of the tested material is measured by slicing the material thinly, and by weighing each of the sliced test pieces. Measured density profiles of the tested materials are compared with the calculated results obtained by a thermal response code. The surface and internal state of both pre- and post- materials are observed by using Scanning Electron Microscope (SEM) and X-ray Computed Tomography (CT). The results show that the measured density profiles is inversely increased to the heated surface. The density increase is likely due to the deposition of a solid carbon in the char region during aerodynamic heating., 資料番号: AA0063742010, レポート番号: JAXA-SP-07-016}, pages = {56--61}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {軽量アブレータの熱応答特性解析}, volume = {JAXA-SP-07-016}, year = {2008} }
