Abstract : A systematic investigation of the behavior of plastic materials in very high temperature air is reported. Several test models of various compositions and constructions were exposed in the air plasma of a one megawatt stabilized electric arc. Both descriptive and quantitative data were obtained on the characteristics and physical properties of the ablative materials. A thermal analysis of quasi steady-state ablation at the stagnation point of the test models was performed. Individual heat transfer parameters were numerically estimated for the plastic materials and test conditions under consideration. (Author-PL).
