树脂在纸基摩擦材料中分布规律的研究
Study on the Distribution of Resin in Paper-based Friction Materials
摘要
Abstract
Structure and properties of paper-based friction materials are essentially affected by their surface and internal resins,and the uni-formity of resin distribution determines the interaction among the internal components of paper-based friction materials,thus affecting the overall physico chemical properties.In order to realize the uniform distribution of resin in paper-based friction materials,the effect of resin content on the Z direction distribution(from mesh to blanket)of resin in paper-based friction materials was investigated.The results showed that with the increase of resin solution mass fraction,the resin content of paper-based friction materials increased,and the porosity and aver-age pore size decreased.According to the difference of X-ray absorption degree of each component in paper-based friction material,the resin content was measured.When the resin content was low and the volume proportion was about 7%,the resin was evenly distributed in the Z di-rection of the paper-based friction material.With the increase of resin content,due to the uneven distribution of fibers,fillers,and pores in the base paper,the Z direction distribution of the resin in the paper-based friction material was uneven,and the two-sided difference of the resin content of the paper-based friction material increased.When the resin content in the paper-based friction material was high,the resin further occupied the available space occupied by air inside the paper-based friction material,resulting in the continuous increase of the resin inside the paper-based friction material,but the difference between the two sides of the resin content was only 0.5%.关键词
