Carbon-based nanomaterials mainly including carbon nanotubes (CNTs), graphene, and graphene oxide (GO) have superior properties of low density, outstanding strength, high hardness. Compared with ceramic reinforcements, small amount carbon-based can significantly improve the mechanical metal matrix composites (MMCs) (CMCs). However, CNTs graphite always aggregate or degrade during fabrication a ...

Abstract To explore the influence of path deflection on crack propagation, a planning algorithm is presented to calculate growth length. The fatigue life metal matrix composites (MMCs) estimated based an improved Paris formula. Considering different expansion coefficient materials, unequal shrinkage will lead residual stress when composite molded and cooled. model by modified ratio stress. Dijk...

High modulus of about 1 TPa, high thermal conductivity over 3000 W/mK, very low coefficient expansion (CTE), electrical conductivity, self-lubricating characteristics and density have made CNTs one the best reinforcing materials nano composites for advanced structural, industrial, strength wear-prone applications. This is so because it has capacity improving mechanical, tribological, electrical...
