摘要: Heat insulating component consists of a made from metallic support (1) having front surface (3) subjected to temperatures more than 700 deg C and cooled rear (4). Ceramic fibers (2) aligned vertically the are fixed on surface, network parallel gaps joined together is formed between fibers. Preferred Features: The an oxide ceramic, preferably aluminum oxide, zirconium silicon magnesium and/or titanium oxide. have round, oval or polygonal cross-section. pores with porosity 1-90 %.
