Paper Title:
Effect of Formation Nonuniformity on the Mechanical Strength of Aramid Paper
  Abstract

Aramid paper was manufactured using poly (m-phenyleneisophthalamide) (PMIA) fibers and fibrids, and poly(ethylene oxide) (PEO) was used as dispersant to improve the uniformity of fiber distribution. The Paper Perfect Formation Analyzer (PPF) and the BFT-1 type β Formation tester were used to determine the formation of the aramid paper, and the relationship between the formation and the mechanical strength of aramid paper was discussed. Results showed that the tensile strength and tear strength of aramid paper before hot calendering is affected strongly by its grammage standard deviation, but is less affected by its formation nonuniformity as a function of the scale of foramtion, the R2 correlation between tensile strength and grammage standard deviation was 0.63, and the R2 correlation between tear strength and grammage standard deviation was 0.73. However, the nonuniformity of formation in the range of scale of formation 0.8-22.7mm has great influence on the tensile strength of aramid paper after hot calendering, and the R2 correlation between tensile strength and formation nonuniformity in this range of scale of formation was greater than 0.58.
