| Abstract Scope |
Silicon carbide (SiC) is useful for high-temperature applications due to its corrosion resistance and strength retention at elevated temperatures. Often the components needed for high-temperature applications are complex and difficult to manufacture. To decrease production costs these complex parts are often created by joining simpler geometries together. One approach to forming SiC powders involves blending it with a thermoplastic polymer followed by extrusion of the mixture above the T<sub>g </sub>of the polymer. These extrudates are then joined to create useful shapes. In this study, a blend of SiC/polymers composed of Polyethylene Glycol, Heavy Mineral Oil, Ethylene Ethyl Acrylate, and Poly (Isobutyl Methacrylate) were joined together. A variety of temperatures (100°C-150°C), pressures (0.1-1MPa), and hold times (60-600 mins) were used to determine the viability of SiC green state joining before burnout and sintering. The joints were then characterized by mechanical testing and SEM microscopy to gain insight into the joint strength. |
