The main aim of present research was to develop a new low-cost synthesis route produce ultralight Al2O3 cryogel – fiber composite materials for high temperature insulation. fibers give the matrix in these composites, instead typical reinforcement phase. precursor systems drawing and freeze drying is based on sol–gel chemistry. starting (inorganic Al salts, organic solvents, additives) were same both type porous systems. length (5–10 cm) sufficient form composites. average diameter 10 µm;...
Abstract The eventual aim of this research work was to develop a new low-cost synthesis route produce ultralight aluminum oxide ceramic fibers for high temperature insulation. This paper mainly focuses on the application Al 2 O 3 as insulation materials in space vehicles. study extended check during launch and conditions by satellite test. were monitored thermo-vacuum vibration tests before launch. long-term stability, daily maximum minimum temperature, fluctuation investigated data derived...
Pure aluminium oxide vacuum-formed fibreboards were obtained from new generation of alumina fibres synthesized by the sol-gel method. The effect chemical composition and particle size binder on boards was examined. High-temperature testing took place at 1500 °C for 24 h. mechanical properties (both modulus compressive strength) are better with Boehmite than hydroxide. Decreasing particles enhances these properties. Field emission scanning electron microscopy used to study micro-scale...
