초록
The uniformly dispersed Aramid and Poly (phenylene benzobisoxazole) (PBO) in a variety of rubber was investigated. The mechanical properties of rubber were characterized by hardness, tensile strength, elongation at break, heat resistance, oil resistance, cold resistance, ozone resistance measurements. The 3mm Aramid chopped fiber better tensile strength than the other Chopped fiber. The Aramid of 3mm chopped fiber showed excellent reinforcing in rubber composite because of homogeneous dispersion. Consequently, the best 3mm Aramid chopped fiber and rubber improved the tensile strength and elongation at break of the composite. Also, 3mm Aramid chopped fiber improved the oil-resistant, ozone resistant and cold resistant.
