dc.description.abstractIn this work, the manufacturing process for employing patented Ceramic Nano-Paste composite Silicon Carbide (SiC) based materials in various parts and shapes using Polymer Infiltration and Pyrolysis (PIP) method are studied. Applications include optical, ballistic, electrical, and mechanical structures and components. The Nano-Paste nanocomposite used in this research consists of two constituents: a matrix and reinforcement fillers. For all of the projects in this research, SMP-10 preceramic polymer was used as the matrix, with SMP-850 preceramic polymer added during the infiltration process for some applications. The reinforcement fillers used was dependent on the application, with β-SiC (2 µm) and B4C (2 µm) being the primary fillers with the addition of the following materials for various applications: β-SiC (50 nm), SiC whisker (Diameter 0.1-2.5 µm, length 2.0-50 µm), Si (400 nm), B4C (2 µm), B6O (2 µm), BN (137 nm), MWCNT (O.D. 10-30 nm, length 10-30 µm), and carbon short fibers (1-5 mm). A new process for determining the filler to matrix volume ratios was developed, in this work, using volume compaction efficiency technique. With the use of relatively low-pressure (3-202 MPa) z-plane compaction molding, low temperature curing (100-200 °C), abrasive cutting, and Nano-Paste joining, complicated shapes and parts are manufacturable employing this Additive Manufacturing technique before serimizing the cured preceramic polymer matrix of the parts at 1,000 °C. This Additive Manufacturing approach eliminates the need for subtractive machining on ceramics to produce complex shapes while also introducing an easy way to include additives to create novelty engineered materials.
