Hybrid Mineral Fibre Thermal Insulation Systems
topic
Multilayer hybrid insulation systems combine aerogel blankets, microporous silica, alumino-silicate ceramic fibre, and metal foil radiation shields in optimised layer sequences that provide minimum thermal conductivity across temperature gradients from ambient to high-temperature hot face, with each layer material selected for its thermal performance in its specific temperature range within the overall system.
Role
Achieves total insulation system thermal performance significantly better than any single insulation material by combining materials optimised for different heat transfer regimes, with aerogel or microporous silica minimising conduction, metal foil shields minimising radiation at intermediate temperatures, and ceramic fibre providing structural integrity and insulation at the hot face.
