Abstract
Abstract A method of manufacturing aromatic polyamide fiber reinforced rubber composite. in one embodiment, the aromatic polyamide fiber is immersed in a solution of epoxy resin denatured with urethane prior to bonding to the subsequently vulcanized rubber compound. In another embodiment, the fiber is further treated before associated with the rubber compound by immersion in a liquid formed of a mixture of initial condensate of resorcinol and formalin, and rubber latex, wherein the mole ratio of the resorcinol to formalin is in the range of 1 to 0.5 to 3. The dried treated fiber may be stored as desired for facilitated manufacture of the fiber bonded rubber composites.
