    • PURPOSE: A non-asbestos system frictional element is provided to reduce a molding periodic time by having an excellent promptly hardening property and not to make a noise essentially while braking. CONSTITUTION: A non-asbestos system frictional element is formed by molding and hardening a composition including a fiber base, a binder, and a filling material. The frictional material has a value more than -0.030 for the difference subtracting 100 Hz vibrating damping factor in a temperature of 50°C from 100 Hz vibrating damping factor in a temperature of 300°C. Herein, the binder can be formed by a rubber regenerated high-ortho phenol resin, a resin mixture of the rubber regenerated high-ortho phenol resin and a rubber regenerated phenol resin, or resin mixture of more than two rubber regenerated phenol resins. Therefore, the frictional material has excellent noise property for a long time and abrasion resistance.
    • 目的:提供非石棉系摩擦元件,通过具有优异的快速硬化性能,在制动时基本不产生噪音来减少成型周期时间。 构成:通过对包含纤维基材,粘合剂和填充材料的组合物进行成型和硬化来形成非石棉系摩擦元件。 在温度为300℃的100Hz振动阻尼因子中,在50℃的温度下减去100Hz振动阻尼系数的差值大于-0.030。 这里,粘合剂可以由橡胶再生高邻苯酚树脂,橡胶再生高邻苯酚树脂和橡胶再生酚醛树脂的树脂混合物,或多于两种的橡胶再生酚醛树脂的树脂混合物形成。 因此,摩擦材料长期具有优异的噪声特性和耐磨性。
