Abstract : The place of reinforced plastics for applications in hyperthermal environments is established. However, it has been discovered that no single system is applicable generally inasmuch as ablation rate is controlled by the environment as well as by the materials and manufacturing techniques. Further, ablation rate is not the only important property of nose cone insulation material. Surface conditions during re-entry, mechanical and electrical properties of the material, and manufacturing feasibility are important considerations. Since the efficiency of reinforced plastic ablation systems increases with increasing heating rate, there is no practical upper limit to the thermal environment for which reinforced plastics might be applicable.
