Silicon Carbide CNT Composite: Carbon nanotubes (CNTs) have great potential for a variety of applications out of which composite reinforcement is the most promising one. Silicon carbide (SiC) with its unique properties is expected to enable significant enhancements in the existing properties of CNTs to a far-ranging variety of applications and systems.

Silicon Carbide CNT Composite: Silicon carbide based advanced ceramics are the leading materials for a number of applications in aeronautics, energy, electronics, nuclear, and transportation industries. Specifically SiC based materials are able to preserve durable working capability when exposed to radiation at high temperatures and in aggressive environments. Silicon carbide ceramics have high stiffness and excellent thermal stability with low density, but their brittleness impedes their use as structural materials. Because of their exceptional resilience, carbon nanotubes (CNTs) might be desirable as reinforcement for ceramics. The combination of these nanotubes with a ceramic matrix could potentially create composites that have high temperature stability as well as exceptional toughness and creep resistance.

Silicon Carbide CNT Composite: Due to the extraordinary electronic, mechanical, chemical, thermal, magnetic, and optical properties, carbon nanotube (CNT), an excellent one-dimensional nano-material, has been considered as a new filler for polymer, metal, and ceramic matrix composites with the main purpose of improving their mechanical performance, fracture behavior, and functional features. In the silicon carbide (SiC) ceramic field, there are many CNT reinforced SiC ceramic matrix composites and CNT/SiC hybrid structures, which have been investigated successfully using various of methods.

Silicon Carbide CNT Composite: Carbon nanotubes reinforced composites have been processed by various techniques such as conventional powder metallurgy, cold and Hot Isostatic Pressing (HIP), Spark Plasma Sintering (SPS), Equal Channel Angular Pressing (ECAP), and planar shock-wave compaction. Copper-based Nanocomposites reinforced with 12-15vol % CNTs were developed by well-established powder metallurgy to study microhardness and tribological properties. The microhardness of composite was found to be in the range of 100-115 HV. Microhardness was increased with increase in carbon nanotube content till 15 vol.% and then start reducing due to agglomeration and porosity. Significant reduction in friction and wear loss was observed with increase in carbon nanotube due to its lubrication behavior and tribolayer formed between composite and counter surface
