Abstract

We fabricated MWNT-added glass fabric/epoxy composites. We observed the distribution of MWNTs in the composites using scanning electron microscopy and conformed that most of MWNTs exist in matrix rich region and interface between yams in warp and fill directions. We also investigated the change of permittivities with MWNT concentrations. Only $1wt\%$ MWNTs leads to high permittivity and electromagnetic waves are impossible to be transmitted to more than $3wt\%$ MWNT-added composites, which means the characteristics of these composites are comparable to those of metals or carbon fiber-reinforced composites.
