Abstract
A process for producing a nanographene platelet-reinforced composite material having nanographene platelets or sheets (NGPs) as a first reinforcement phase dispersed in a matrix material and the first reinforcement phase occupies a weight fraction of 1-90% based on the total composite weight. Preferably, these NGPs, alone or in combination with a second reinforcement phase, are bonded by an adhesive and constitute a continuous 3-D network of electron- and phonon-conducting paths.

A process for producing a nanographene platelet-reinforced composite material comprising
- (a) providing a plurality of nanographene platelets;
- (b) bonding said nanographene platelets with an adhesive material to form a porous preform having a three-dimensional network of continuous electron- and phonon-conducting paths;
- (c) impregnating said porous preform with a matrix material to form an impregnated preform;
- and
- (d) solidifying said impregnated preform to produce said nanographene platelet-reinforced composite material.
