TECHNICAL ABSTRACT (LIMIT 200 WORDS)
The proposed innovation is to use combustion synthesis techniques to manufacture ceramic-based acoustic liners capable of withstanding temperatures up to 2500?C. Combustion synthesis or self-propagating high temperature synthesis (SHS) is a novel technique used by Guigne Space Systems Inc. to produce many advanced high-temperature materials and composites. The materials have a ceramic matrix (alumina Al2O3, MgO, Al2O3-MgO, TiC-Al2O3, or Al2O3-TiB2) and exhibit high porosity. These materials can also be fabricated with a functional gradient, i.e., with a change in chemistry and/or porosity within the same sample. When compared to traditional manufacturing techniques for high-temperature materials, combustion synthesis has the advantages of energy and time saving methods, high purity final product, simplicity of process and low cost. The target application for the porous ceramics is as high temperature acoustic liners for noise reduction in rocket and jet engines. The proposed work is Phase I of the project.
POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
