Silicon Carbide Coated Graphite Derived from Chlorine Free Preceramic Polymer Precursor

Ordered mesoporous silicon carbide (OM-SiC) via polymer precursor nanocasting.

Ordered mesoporous SiC with high specific surface area (650-800 m(2) g(-1)) and well ordered pore structure was obtained via nanocasting of polycarbosilanes into SBA-15 and subsequent conversion of the polymer at 1300 degrees C.

Etching of Silicon Carbide Using Chlorine Trifluoride Gas

Single Point Diamond Turning of CVD coated Silicon Carbide

Scratching experiments, using diamond styli and single point diamond tools, were performed to simulate Single Point Diamond Turning (SPDT). The results of these experiments were used to determine if a ductile response is possible, and then to determine the critical depth of cut or penetration depth for the ductile to brittle transition (DBT). The depths of the scratches produced at different lo...

Finite Element Modeling of the Vibrational Behavior of Single-Walled Silicon Carbide Nanotube/Polymer Nanocomposites

The multi-scale finite element method is used to study the vibrational characteristics of polymer matrix reinforced by single-walled silicon carbide nanotubes. For this purpose, the nanoscale finite element method is employed to simulate the nanotubes at the nanoscale. While, the polymer is considered as a continuum at the larger scale. The polymer nanotube interphase is simulated by spring ele...

Preparation and Characterization of Continuous Fe-Containing Silicon Carbide Radar Absorbing Fibers from Precursor-Based Processing

A new polymer polyferrocarbosilane (PFCS) was synthesized using polydimethylsilane and ferrocene as the raw materials. The polymer was then melt-spun into continuous PFCS fibers, cured in air and heat-treated in a nitrogen atmosphere up to 1300 , a kind of Fe-containing SiC fibers were finally obtained. The SiC(Fe) ceramic fibers were combined with epoxy resin and a structural material was prep...
