摘要:采用碳纤维、短切芳纶纤维、芳纶浆粕、竹纤维以及海泡石绒为原料，并用抄纸的方法抄造纸基摩擦材料原纸；通过在抄造浆料中添加聚氧化乙烯（PEO）和阳离子聚丙烯酰胺（CPAM），探究了PEO和CPAM对浆料分散性能和纸张匀度和抗张强度的影响。结果表明，PEO对浆料有良好的分散作用，CPAM对纸张有很好的增强效果，当PEO用量为0.2%、CPAM用量为0.16%时，浆料分散效果最好，成纸的匀度最高。

Abstract:The experiment used carbon fiber, chopped Kevlar fiber and aramid pulp, bamboo fiber and sepiolite flocking as raw material to prepare paper based friction material by wet-forming process. Polyethylene oxide (PEO) and cationic polyacrylamides (CPAM) were used as chemical additives and the influence of the dosages of PEO and CPAM on furnish dispersion and the paper formation was studied. The results show that the furnish dispersion and the paper formation were the best when the dosages of PEO and CPAM were 0.2% and 0.16% respectively.
