摘要
随着科技的进步,航空航天技术发展迅速,因此迫切需要长寿命、高精度及高可靠性的含油轴承。多孔聚酰亚胺材料不但具备聚酰亚胺卓越的耐高低温性能、耐辐照性和良好的机械性能等,还拥有多孔材料自润滑、质量轻、密度低等优点,被广泛应用于航空航天等领域。因此,本文系统介绍了多孔聚酰亚胺含油材料的工作特性、研究现状及现存问题,为其进一步研究提供参考。
With the progress of science and technology,aerospace technology is developing rapidly,so there is an urgent need for oil-bearing with long life,high precision and high reliability.Porous polyimide materials not only possess excellent high and low temperature resistance,radiation resistance and good mechanical properties of polyimide,but also have the advantages of self-lubrication,light weight and low density of porous materials,which are widely used in aerospace and other fields.Therefore,the working characteristics,research status and existing problems of porous polyimide oil-bearing materials are systematically introduced in this paper,so as to provide reference for further research of porous polyimide oil-bearing materials.
