ARAMID PAPER SHEET AND METHOD FOR PRODUCING SAME

摘要

An aramid paper sheet which is formed from a mixture of short fibers and fibrids formed from an aromatic polyamide, and which has a content of the fibrids and a thickness satisfying inequality expressions (1) and (2). 40 ≤ (FB) ≤ 90 (1) (Thickness)/((Fiber diameter of short fibers) × 2) ≤ 1.25 (2) (In the formulae, (FB) represents the content (wt%) of the fibrids in the aramid paper sheet.)
