摘要： PROBLEM TO BE SOLVED: To provide a thin layer sheet with higher quality containing pyridobisimidazole fibers as a reinforcing material. SOLUTION: The thin layer contains a pyridobisimidazole fiber with root mean square roughness of the fiber surface of 30 nm or less and a resin. Gaps among fibers can be further reduced when fibers are aligned in uniaxial direction if the root mean square roughness of the fiber surface is small, that is, the fiber surface is smooth. Therefore, the thin sheet with higher quality is obtained. COPYRIGHT: (C)2011,JPO&INPIT
