    Abstract:

    Thermal protect performance of flexible materials was improved by devising the method of thermal pro ̄
    tection. A radiation/ ablation alternate flexible thermal protection materials (FTPM) was designedꎬ which was composed
    of multi layer of composites of heat-resistant and evaluated by oxyacetylene ablation test. In order to eliminate the poor
    adhesion between the radiation layer and ablation layerꎬ the adhesion properties was evaluated by T peel test and SEM
    after modified by surface treatment. The results showed that new FTPM possesses much more excellent ablative perform ̄
    ance than conventional ablatorsꎬ because FTPM has more layers in good condition and lower temperature after ablation
    test. Adhesion properties were improved effectively by surface treatment and obtained the best with 5wt%.
