| Abstract: | This composite material was synthesized by a two-step sol-gel. TEOS was used as precursor, ethanol and water were used as solvent, mullite fiber was used as reinforced material. After the Sol-gel process and surface modification, atmospheric pressure and vacuum drying process were used to get this composite material. With TPS1500-thermal Conductivity Instrument, the influence of the fiber was tested and analyze. |
