<p>A novel aramid honeycombs 11 and a method therefor are provided, wherein aramid sheets 1 are used as the base material for forming cell walls 18 of the honeycombs 11. The aramid sheets 1 comprise para-aramid pulps 2, an amount of 40% by weight or less of para-aramid fibers 3 and a binder 4. Each of the aramid sheets 1 is calendered to produce pores 9, which extend from the outer surface to inside, with a porosity of 20 % to 60%. Further, a reinforcing resin 10 is adhered to the cell walls 18 of the aramid sheets 1 and the pores are filled with the resin in an amount of 50% by volume based on the pore volume.</p> |
