摘　　要：以单醚酐型聚酰亚胺和均苯型聚酰亚胺共混,采用限位热压烧结的方法得到轴承组件用控流芯阀材料,通过工艺控制其孔径、孔隙率,并对其微孔性能、力学性能以及供油性能进行研究。结果表明:该芯阀材料可形成均匀孔道,孔径集中分布在0.01~0.50μm之间,额定功率下供油速率为0.2~0.3 mg/d,预测寿命可达18~27年。The material of restrictor for bearing assembly is prepared by blending monoether anhydride polyimide and homophenylene polyimide and adopting limiting hot pressing sintering method. The pore size and porosity can be controlled by process, and its microporous performance, mechanical properties and oil supply performance are studied. The results show that the material of restrictor has uniform pore structure with pore size in a range of 0.01~0.50 μm, the oil supply rate is 0.2~0.3 mg/d at rated power, the predicted life is 18~27 years.
