Carbon/Carbon comparative optimization method for hot structures application in re-entry environment conditions

ABSTRACT Hot structures applications have becoming more and more widespread, from space to nuclear sectors. Carbon/Carbon is one of the best materials for hot structures. It has good characteristics, particularly adapted to operate in re-entry environments with high resistance, high elongation modulus, high mechanical property at high temperature and very low CTE. The key factor for using this kind of material is the high stability at high temperature, preserving its mechanical properties. Here is presented a mathematical model for C/C production optimized by a genetic algorithms. The manufactured specimens are then characterized by the use of the inverse method. The general method of iterative regularization is concerned with application to the estimation of materials properties. Such problems are of great practical importance in the study of material properties used as non-destructive surface shield in objects of space engineering, power engineering, etc.
