Abstract : An analytical technique has been developed to predict the thermomechanical erosion of plastic composite materials for reentry nose tip application. The method presented requires empirically derived material property data which has been obtained for reverse chevron carbon phenolic from a series of 50 MW arc tests. The method has been used to predict the ablation behavior of similar materials in other test environments and is shown to be in reasonable agreement with the measured data. (Author, modified-PL)
