Abstract
A thermal protection structure includes a thermal protection layer formed by impregnating reinforcing fibers with a matrix resin, a gas-pervious wear-resistant layer formed of a heat-resistant material and laminated on the outer surface to be exposed to heat of the thermal protection layer. The wear-resistant layer prevents the direct impact of raindrops or ice pellets on the thermal protection layer, so that the reduction of the thermal protection ability of the thermal protection layer due to wear can be prevented. The gas-pervious wear-resistant layer permits the emission of gases produced by the thermal decomposition and carbonization of the thermal protection layer caused by aerodynamic heating into the environment.
