Outline of Final Research Achievements

By identifying the generation mechanism of delamination during rapid heating of CFRP ablator and carrying out numerical simulation, we have established a method that enables quantitative prediction of delamination generation. In the numerical analysis, multiphysics coupled analysis of heat conduction, chemical reaction such as carbonization, flow of generated gas, and separation generation by internal pressure was performed. As a result of examining the validity of the numerical simulation results using the arc wind tunnel owned by JAXA, good agreement was obtained between experiment and analysis. We learned the technology that can predict the occurrence of delamination in an unknown environment.

Academic Significance and Societal Importance of the Research Achievements
