A lightweight ablator formulation has been developed which offers superior thermal performance compared to current state of the art ablator formulations. The lightweight ablator formulations described herein typically include at least one endothermically decomposing (energy absorbing) material with a fluxing agent resulting in significantly reduced backface temperature response and a more stable surface. According to one implementation the ablator composition comprises about 30 to about 70 percent by weight of a base silicone resin, about 25 to about 67 percent by weight of a low-density filler, about 3 to about 7 percent by weight of a curing agent and greater than 0 and up to about 10 percent by weight of a boron-containing compound.

A thermal protection system is provided for a vehicle substructure. The thermal protection system comprises an outer layer for protecting the vehicle substructure. The thermal protection system further comprises an inner layer for conforming to the vehicle substructure. The thermal protection system also comprises an insulation layer sandwiched between the inner and outer layers. The insulation layer includes a porous low-density ceramic insulating material having a densified portion that covers an inner surface of the outer layer to strengthen adhesion.

A method of forming a thermal protection system for high speed aircraft is described. The method includes mechanically working an uncured ablator material into a first surface of a felt layer such that the ablator material penetrates a distance into a thickness of the felt layer thereby forming an region that has a mixture of felt and ablator material, adding additional uncured ablator material to the worked ablator material, and curing the combined ablator material.
