Patent ID: 8764941

Claim:
A base paper of aramid fiber honeycomb core, comprising: structural fiber; crosslinking fiber; and additive fiber; wherein said structural fiber is poly(p-phenylene terephthal amide) fiber at 65 parts by weight, said crosslinking fiber is poly(m-phenylene isophthal amide) fibrid at 20 parts by weight, and said additive fiber is polyester fiber is poly(ethylene glycol terephthalate) fiber at 15 parts by weight; wherein said base paper of aramid fiber honeycomb core is prepared by subjecting to papermaking shaping of structural fiber, crosslinking fiber and additive fiber via wet papermaking, and hot rolling; and wherein said hot rolling is dual temperature dual pressure zone hot rolling, in a first group, the linear pressure of hot rolling is 0˜100 kg/cm, the surface temperature of the roller is 240˜255° C., the rolling speed is 3˜30 m/min; in a second group, the linear pressure of hot rolling is 30˜250 kg/cm, the surface temperature of the roller is 180˜230° C., the rolling speed is 3˜30 m/min.
