Progress of the Current Interface Research on Carbon Nanotubes Reinforced Aluminum-Matrix Composites

Abstract

The carbon nanotubes with its stable structure, excellent mechanical properties, become the ideal enhancement phase of composite materials. The enhancement effect is affected by various factors, interface is one of the key factors determine its enhancement effect, also is the research focus of metal matrix composites. Briefly introduced carbon nanotubes reinforced aluminum matrix (CNTs/Al) composite material interface bonding mechanism and interface effect on the properties of composite materials, thermal expansion coefficient and preparation methods were reviewed, purity of carbon nanotubes and other factors impact on CNTs/Alcomposites interface, and puts forward the way to improve interface.

Microstructure Dependent Dislocation Density Evolution in Micro-macro Rolled CNT/Al Composite

“…Former is composed of dispersion and extent of reaction and the latter regards shape, size, and texture of matrix grain [3][4][5][6][7][8][9]. To meet simultaneously all of the parameters, a large number of methods are proposed [4,[10][11][12][13][14][15][16] which among all these techniques flake powder metallurgy (flake PM) had been attained much more attention [3,15,17]. Jiang et al [3] showed that flake powder metallurgy is an effective route to achieve a uniform dispersion of CNTs with very little structure damage in the Al matrix.…”
