NOVELTY - A fiber mat absorbing material comprises 20-40 pts. wt. epoxy resin base, 2-5 pts. wt. curing agent, 20-30 pts. wt. graphene fiber, 10-20 pts. wt. carbon black and 5-15 pts. wt. microwave absorbent fiber bundle. The graphene fiber-coated carbon black forms a composite graphene fiber, and acts with the epoxy resin base and curing agent to form a graphene fiber mat. The microwave absorbent fiber bundle consists of iron oxide microwave absorber, polyaniline and glass fiber which are uniformly mixed in a weight ratio of 1:(0.2-0.5):(0.5-2) to form a fiber bundle of 0.1-1 mm. USE - Fiber mat absorbing material (claimed). ADVANTAGE - The fiber mat absorbing material has reflection attenuation of greater than -28 dB at 10-18 GHz. DETAILED DESCRIPTION - A fiber mat absorbing material comprises 20-40 pts. wt. epoxy resin base, 2-5 pts. wt. curing agent, 20-30 pts. wt. graphene fiber, 10-20 pts. wt. carbon black and 5-15 pts. wt. microwave absorbent fiber bundle. The graphene fiber-coated carbon black forms a composite graphene fiber, and acts with the epoxy resin base and curing agent to form a graphene fiber mat. The microwave absorbent fiber bundle consists of iron oxide microwave absorber, polyaniline and glass fiber which are uniformly mixed in a weight ratio of 1:(0.2-0.5):(0.5-2) to form a fiber bundle of 0.1-1 mm. The microwave absorbent fiber bundle is vertically dispersed in the epoxy resin to form an equidistant array which has pitch of not more than 10 mm.
