Abstract
Thermal protection material coating of an aggregate of mineral fibers, in particular carbon or silicon, is provided with at least one coat of a silicon-based material covering at least the area exposable to the flaking or crumbling sources of the thermal protection device. The coating is especially applicable to thermal protection structures.
Claims11
A coating, comprising:
- a thermic protection material comprising an aggregate containing mineral fibers, said aggregate including a surface which is capable of crumbling under action of gaseous flow thereover;
- and
- at least one layer of a silicone-based material covering at least said surface, said silicone-based material comprising at least one member selected from the group consisting of certified space products.
A coating, comprising:
- a thermic protection material comprising an aggregate containing mineral fibers, said aggregate including a surface which is capable of crumbling under action of gaseous flow thereover;
- and
- at least one layer of a silicone-based material covering at least said surface, said silicone-based material is not selected from the group consisting of certified space products, and is subjected, after projection and polymerization on said surface, to a baking post-treatment such that after the baking post-treatment, the silicone-based material fulfills the requirements of degassing standard ESA PSS 01-702A.
