Abstract
Arrangement for the thermal protection of an object, particularly a space vehicle, such as a space missile, including a frame structure covered with thermal insulating material, wherein the material is made of an aggregate of carbon or silica short fibers, the fibers being linked together by means of a binder made of the same constituent and possibly of an appropriate resin. The aggregate is in the form of at least one monobloc element, which is accordingly shaped and dimensioned, and adhered onto the frame structure.
Claims13
An arrangement for thermal protection of an object, comprising:
- a frame structure;
- thermal insulating material covering said frame structure, said thermal insulating material comprising a porous aggregate of fibers selected from the group consisting of carbon short fibers and silica short fibers, said fibers comprising a diameter of less than or equal to 10 micrometers, and a length less than or equal to 700 micrometers;
- a binder linking said fibers together, said binder comprising the same constituent as said fibers;
- and
- said aggregate comprising a specific gravity of between about 0.2 and 0.5, and is in the form of at least one monobloc element, said at least one monobloc element is attached to a surface of said frame structure, and a fixing adhesive layer is discontinuously positioned between inner faces of said plurality of slabs and said surface of said frame structure.
