【摘要】：采用原位聚合法制备出厚度约为100μm的聚酰亚胺薄膜,激光熔融法在薄膜表面刻蚀出不同形状的表面织构。研究表面织构对聚酰亚胺薄膜力学性能及摩擦学性能的影响。测试了不同形式的织构对超声电机机械输出性能的影响。结果表明,织构的存在,使得薄膜的拉伸强度有所降低;摩擦系数降低,且摩擦系数更加稳定,磨损率有所降低,使得超声电机机械输出性能更加稳定。
[Abstract]:Polyimide films with a thickness of about 100 渭 m were prepared by in-situ polymerization. The surface textures of different shapes were etched by laser melting method on the surface of the films. The effect of surface texture on the mechanical and tribological properties of polyimide films was investigated. The effect of different textures on the mechanical output performance of ultrasonic motor was tested. The results show that the tensile strength of the film decreases, the friction coefficient becomes more stable and the wear rate decreases, which makes the mechanical output performance of ultrasonic motor more stable.
