▎ 摘　　要

NOVELTY - A fiber-based wave-absorbing material comprises 40-60 pts. wt. epoxy resin matrix, 2-10 pts. wt. curing agent, 10-30 pts. wt. graphene fiber and 5-15 pts. wt. barium ferrite (BaFe12O19) microwave absorber. The graphene fiber is graphene fiber bundles which are vertically dispersed in epoxy resin so as to form an equidistant array. The barium ferrite microwave absorber is uniformly dispersed in the epoxy resin. USE - Fiber-based wave-absorbing material (claimed). ADVANTAGE - The fiber-based wave-absorbing material has reflection attenuation of greater than -27 db at 10-18 GHz.
