| Abstract Scope |
Ceramic fibers present unique solutions for high-temperature, high-stress applications including thruster nozzles, nuclear reactors, and combustion gas turbine engines. Silicon carbide fibers exhibit excellent thermomechanical properties that allow them to maintain impressive Young’s moduli at temperatures exceeding 1000°C, while still being lighter and less dense than metals with comparable mechanical properties. Three varieties of these fibers were compared to determine optimal performance within fiber-reinforced polymer matrix composites for future research involving the fabrication of ceramic matrix composites. Tensile testing was performed to review the Young’s moduli and tensile strengths of both chopped fiber-filler and continuous fiber composites in order to fairly compare mechanical improvements made by each SiC fiber. The three types of SiC fibers tested were Hi-Nicalon Type S, Sylramic, and Tyranno SA3. The matrix for each composite was a 635 thin epoxy resin mixed with a 3:1 epoxy hardener. |
