Refined thermophysical property testing method for ablative silicone rubber thermal protection material

The invention discloses a refined thermophysical property testing method for an ablation type silicone rubber thermal protection material, and mainly relates to a refined testing method for key thermophysical properties such as density, specific heat capacity and heat conductivity of a silicone rubber-based thermal protection material in different ablation stages. Comprising the following steps: (1) preparing silicone rubber materials in different ablation stages; (2) density change rules of the silicone rubber material in different ablation stages; (3) specific heat capacity change rules of the silicone rubber material in different ablation stages; and (4) heat conductivity change rules of the silicone rubber material in different ablation stages. The invention provides a fine characterization method which is simple and easy to implement and can be used for finely testing the thermophysical properties of the ablation type silicon rubber thermal protection material in the ablation process. 本发明公开了一种面向烧蚀型硅橡胶热防护
