First claim
Opening claim text (preview).
The invention claimed is: 1. A heat protection ablative material for protecting a surface of a space vehicle from heat, having a mixture comprising a phenolic resin with a content of coke above 50% when heated to 1,000° C. in an inert atmosphere such as nitrogen, cork granules and refractory fibers, in which the proportion of cork granules in the mixture is a percentage from 70 to 73% by mass, wherein the percentage by mass in the mixture of refractory fibers is between 1 and 3% while the percentage by mass in the mixture of resin is the range of 23-25% and the material being so designed to withstand heat flows ranging from 0.5 to 10 MW/m2, and the material contains no microspheres. 2. Heat protection material according to claim 1 , comprising 0.5 to 1.5% percentage by mass of fungicide. 3. Heat protection material according to claim 1 , wherein the cork is flame-proofed cork. 4. Heat protection material according to claim 1 , comprising a density between 0.35 and 0.41 kg/L after degassing. 5. Heat protection material according to claim 1 , comprising a density of 0.38 kg/L after degassing. 6. Heat protection material according to claim 1 , wherein the refractory fibers are carbon fibers between 0.4 and 4 mm long. 7. Heat protection material according to claim 1 , wherein the refractory fibers are alumina fibers between 0.4 and 4 mm long. 8. A heat protection ablative material for protecting a surface of a space vehicle from heat, having a mixture comprising a phenolic resin with a content of coke above 50% when heated to 1,000° C. in an inert atmosphere such as nitrogen, cork granules and refractory fibers, in which the proportion of cork granules in the mixture is a percentage from 65 to 68% by mass, wherein the percentage by mass in the mixture of refractory fibers is between is between 9 and 11% while the percentage by mass in the mixture of resin is the range of 21-24% the material being so designed to withstand heat flows ranging from 0.5 to 10 MW/m2, the material containing no microspheres. 9. Heat protection material according to claim 8 , comprising 0.5 to 1.5% percentage by mass of fungicide. 10. Heat protection material according to claim 8 , wherein the cork is flame-proofed cork. 11. Heat protection material according to claim 8 , comprising a density between 0.35 and 0.41 kg/L after degassing. 12. Heat protection material according to any claim 8 , comprising a density of 0.38 kg/L after degassing. 13. Heat protection material according to claim 8 , wherein the refractory fibers are carbon fibers between 0.4 and 4 mm long. 14. Heat protection material according to claim 8 , wherein the refractory fibers are alumina fibers between 0.4 and 4 mm long.
