Abstract EN
The microstructure of the carbonized layer of the low-density resin-based ablative thermal insulation material is observed, and multiscale unit cell models are established for the residual carbon deposition mode of a carbonization process, and then the thermal conductivity coefficient is predicted using the finite element method.
The heat transfer characteristics of a carbonized material are discussed and studied.
The results show that among the several models established, the thermal conductivity coefficient obtained by the cross-linked model of matrix carbonization is more accurate, and the deviation compared with the experimental results is within 20%, which is more consistent with the actual heat transfer mechanism.
At the same time, the finite element random model is used to predict the thermal conductivity coefficient.
The results show that the deviation between the numerical results and the experimentally measured thermal conductivity coefficient of the carbonized layer is within 10%, showing that the accuracy of the finite element random model is significantly higher than that of the dual-scale unit cell model.
The carbon deposition model can accurately predict the heat transfer characteristics of the carbonized layer.
