Abstract
Polyimide fibers and polyamide acid fibers was used as main materials to produce Polyimide fiber paper. A certain amount of PEO and aramid pulp was added and the sheet was treated by immersion and hot pressing in specified process. The experimental results showed that when the dosage of PEO and aramid pulp were 0.06% and 6% respectively, the sheet tended to present more excellent strength properties and electrical performance compared with sheet using single polyimide fibers as the main fiber materials.
