Abstract (en)
[origin: EP0579879A1] An expanded graphite sheet of very large mechanical strength can be produced by compressing a graphite expanded to not less than 50 times as large as normal state in average to be 0.02 to 0.3g/cm<3> in bulk density, grounding the compressed graphite particles, preparing a slurry together with a fibrilated aramid pulp fiber, and applying a wet process to the slurry to be prepared into a paper.
