设计并制备了一种三合一云母带材料，并对其力学性能和电气性能进行测试。结果表明：与二合一聚酰亚胺芳纶云母带材料相比，三合一云母带的力学性能更加优异，击穿电压与二合一云母带相当，采用三合一云母带制备的模拟线棒热态介损低于8%。因此三合一云母带可以作为一种低成本替代材料用于低压电机的制造。
A triad mica tape material was designed and prepared, and its mechanical properties and electri-cal properties were tested. The results show that comparing with the polyimide aramid mica tape, the triad mica tape has better mechanical properties and equivalent breakdown voltage. The dielectric loss factor of simulation bars prepared by the triad mica tape material is less than 8%. So the triad mica tape could be used as a kind of low cost alternative material for manufacturing low voltage motor.
