WebOct 1, 2024 · Concept TPS features two materials, namely the Reinforced Carbon-Carbon Composite (RCC) and the High-Temperature Reusable Surface Insulation (HRSI) made of coated LI-900 Silica ceramics [32]. RCC material is used for nose, wing leading edges, and concept belly side; while HRSI material shields the remaining concept's surface, see Fig. 7. WebAn uncoated HRSI tile held in the hand feels like a very light foam, less dense than styrofoam, and the delicate, friable material must be handled with extreme care to prevent damage. The coating feels like a thin, hard shell and encapsulates the white insulating ceramic to resolve its friability, except on the uncoated side.
