机械振动不仅引起材料的疲劳破坏,而且还会产生噪声。为控制有害的机械振动,人们做出了许多努力。其中,使用具有高损耗系数的聚合物是一种比较通用的阻尼方法。但无论单一聚合物,还是互穿聚合物网络(IPN),都很难同时满足对阻尼材料的以下两个要求:宽的阻尼温度和频率范围,高的 Mechanical vibration not only causes fatigue damage to the material but also produces noise. Much effort has been made to control harmful mechanical vibrations. Among them, the use of polymers with high loss factor is a more general damping method. However, no matter single polymer or interpenetrating polymer network (IPN), it is difficult to meet the following two requirements for damping materials at the same time: wide damping temperature and frequency range, high
