Special Issue Information

Dear Colleagues,

Thermal protection materials have been a very active field of research in the last few decades with the development of hypersonic vehicles. Significant advances in this field have been achieved as a result of interdisciplinary research related to new thermal protection materials, materials fabrication, aerodynamic heating, the ablation mechanism, and numerical methods.

This Special Issue on “Advances in Thermal Protection Composite Materials: Fabrication, Structures, Properties, and Applications” intends to collect the latest developments in this field, written by well-known researchers who have contributed significantly in the numerical simulation, material fabrication, characterization of thermal protection composites, and materials properties as well as other applications.

Topics addressed in this Special Issue may include, but are not limited to:

  • Numerical simulation
  • Aerodynamic heating
  • The ablation mechanism
  • Materials fabrication
  • Material properties
  • Industrial applications

In order to improve the ablation resistance of C/C composites, an AlSiB alloy (mass ratio of Al/Si/B = 2:4:1) was used as a dissipative agent to fill the pores of a C/C composites matrix by reactive melt infiltration to prepare AlSiB-C/C composites. The microstructure evolution and ablation behavior of the obtained AlSiB-C/C composites (mass ratio of Al/Si/B = 2:4:1) under oxy-acetylene flame were investigated by SEM after ablating for 25 s, 50 s, 100 s and 150 s. At the beginning of the ablation process, thermal chemical erosion played a leading part. By using the heat-absorption effect of sweating and the sealing protection effect of the oxide layer, AlSiB-C/C composites significantly reduced the ablation surface temperature, and the linear ablation rate was 4.04 μm/s. With the process of ablation, thermal mechanical erosion tended to dominate. The specimen surface could not form a continuous covering of oxide film to slow down the flame scour, resulting in non-uniform ablation and further expansion of the ablation pit. The self-transpiration cooling behavior and the self-sealing of the ablation products of the dissipative agent played an important role in reducing the extent of thermal chemical erosion and preventing matrix ablation.
