Title: Synthesis and Characterization of Silicon Carbide Ceramic Nanofibers
Description:
The Poster Session will be available for browsing throughout CAMX, located in the exhibit hall lobby, across from registration. Winning entries will be announced at the Poster Sessions on Wednesday, September 11, at 1:00 pm and all entrants will be available at this time to answer questions about their research. Silicon carbide (SiC) ceramics are essential in various industries due to their exceptional high-temperature strength, thermal shock resistance, corrosion resistance, and hardness. They are utilized in applications such as abrasives, electronics, mechanical seals, and spacecraft components. This study focuses on fabricating silicon carbide ceramics nanofibers with diameters ranging from 500 to 800 nm. The nanofibers are produced using the electrospinning technique with polycarbosilane polymers, followed by pyrolysis at temperatures between 1100 and 1600 degrees Celsius. The characterization of these nanofibers is conducted using several techniques. A Scanning Electron Microscope (SEM) is employed to determine the orientation and diameter of the fibers. Fourier Transform Infrared (FTIR) spectroscopy is used to analyze the function groups of the nanofibers. Broadband Dielectric Spectroscopy (BbDS) is utilized to study the rotation and relaxation of dipoles, and tensile tests are performed to measure the tensile strength of the nanofibers. These nanofibers are then integrated into SiC-SiC ceramic composites to enhance the mechanical properties. Overall, the objective of this study is to produce silicon carbide nanofibers that significantly improve the performance and durability of SiC ceramics.
