Abstract
A thermal protection system (TPM) for protecting a surface subject to high thermal load comprising a fiber substrate where the substrate is composed of woven or non-woven layers of fibers laminated together, or the substrate is formed by a process of three-dimensional weaving, wherein the fiber substrate has a variable density of fibers, with said density of fibers increasing across the thickness of the TPM, and further wherein the substrate is needled and coupled to an insulation backing.
Claims15
A thermal protection system for protecting a surface subject to high thermal load, comprising:
- a fiber substrate having an external side and an opposite internal side wherein said external side faces the surface;
- wherein said internal side faces the surface;
- wherein said substrate has a variable density of fibers with said density of fibers increasing in a direction going from the external side to the internal side.
