摘要

In this article, nine ablative parameters of ablative composites are estimated using nonlinear inverse methods. The mathematical model of the ablative composite when exposed to a thermally harsh condition has been developed on the basis of the decomposition of the resin and formation of the char layer at a critical temperature. Three zones of virgin material, pyrolysis zone, and char layer along with two moving boundary surfaces are incorporated into the thermal model. The Levenberg-Marquardt method is used for estimating the unknown properties. Considering the nonlinear behavior of the inverse problem and the insulating behavior of the composite, the convergence of the solution method is acceptable and the estimated parameters are reliable.
