The application of vapor-grown carbon fibers (VGCFs) to cement sheets formed by a filtered suction press method was examined. The VGCFs used were prepared in a mixture of benzene and Linz-Donawitz converter gas by the floating catalyst method. The present VGCFs, as well as asbestos, were found to capture cement particles enough to form the cement sheet. The addition of the present VGCFs could not only reinforce the cement sheet but also make it conductive. The cement sheet containing the VGCFs of 10vol% showed the effect of electromagnetic interference shield, which was comparable to that of the commercial polymer sheet containing stainless steel fibers.
