The dynamic and fatigue properties of short-fiber reinforced Chloroprene rubber have been studied as functions of interphase conditions and fiber content. The loss factor and dynamic ratio generally decreased with fiber content and showed different patterns according to interphase conditions. The better interphase condition showed the higher storage modulus(E_1). Therefore, the short-fiber reinforced rubber could have the better isolation in frequency ratio of √<2> min. compared to frequency ratio of √<2> max. The spring constant of rubber decreased about 21% after the fatigue test. On the contrary, that of reinforced rubber increased in all cases. The temperature of matrix increased about 2.5 times and one of reinforced rubber showed 1.7 〜 2 times up after the test. It is found that the better interphase condition, the smaller changing rate of spring constant and the lower specimen temperature at the same fiber content. Double coatings of rubber solution and bonding agent seems to be better interphase condition than a single coating of rubber solution or bonding agent.
