Effective elastic properties for carbon nanotube reinforced composites are obtained through a variety of micromechanics techniques. An embedded carbon nanotube  in  a  polymer  matrix  and  its surrounding  interphase  is  replaced with an equivalent fiber for  predicting  the  mechanical  properties of  the  carbon  nanotube/polymer composite. The effects of an interphase layer between the nan...

In this paper, a new kind of hierarchical tube with a negative Poisson's ratio (NPR) is proposed. The first level tube is constructed by rolling up an auxetic hexagonal honeycomb. Then, the second level tube is produced by substituting the arm of the auxetic sheet with the first level tube and rolling it up. The Nth ( ) level tube can be built recursively. Based on the Euler beam theory, the eq...

Hydrized derivatives of phenylene diamine were reacted with aromatic diacid chloride to give wholly aromatic polyamide/hydrazide compounds with much better solubility in organic solvents thus improving their pressesability. Carbon nano-tubes were used as fillers to enhance their thermal and mechanical properties. The polymers as well as the composite were characterized by spectral and mechanica...
