SHEET-LIKE PREPREG AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To fabricate a carbon fiber prepreg having a low resin amount and a small variation in the resin basis weight, thereby securing the tack property of both prepreg surfaces necessary when being wound, and providing a prepreg having a good quality and a low resin amount. SOLUTION: A sheet-like prepreg has a carbon fiber and a thermosetting resin. The carbon fiber is oriented in one direction so that the mass per unit area becomes 100 to 250 g/m2. The thermosetting resin is present at least on both surfaces of the sheet-like prepreg. The resin mass content of the thermosetting resin accounted for in the sheet-like prepreg is 6 to 10%, and the tack values of both surfaces of the sheet-like prepreg as measured by a method described in the description are≥1.0 N.
