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.
Claims26
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 away from the surface, and wherein said internal side faces the surface;
- wherein said substrate has a variable density of fibers with said density of fibers increase in a direction going from the external side to the internal side.
A thermal protection system for protecting a surface subject to high thermal load, comprising:
- a fiber substrate having an external side and an opposite side wherein said external side faces away from the surface, and wherein said internal side faces the surface, and wherein said substrate is needled in a direction perpendicular to the plane of the internal and external sides.
