POLYMER DERIVED SIC MATERIALS FOR JOINING SILICON CARBIDE COMPOSITES FOR FUSION ENERGY

Book ·
OSTI ID:984274
The fabrication of large or complex silicon carbide-fiber-reinforced silicon carbide (SiC/SiC) components for fusion energy systems requires a method to assemble smaller components that are limited in size by manufacturing constraints. Recently families of polymers that yield inorganic materials subsequent to pyrolysis have been a subject of extensive international research [2-9]. One such polymer, allyl-hydridopolycarbosilane (aHPCS), has been shown to have good high temperature mechanical properties as well as requiring a relatively low temperature for pyrolysis [5]. In this study the mechanical properties of joints fabricated by aHPCS were measured. Preliminary results indicate that the strength value of the aHPCS joints are slightly lower than those of reaction-based methods.
