PRODUCTION OF PREPREG SHEET HAVING DIFFERENT FIBER ANGLE OR LAMINATOR THEREFOR

摘要

PURPOSE:To obtain the subject sheet having a desired fiber oriented angle with a high efficiency by cutting an UD prepreg sheet to the desired fiber oriented angle and automating operation to apply the cut prepreg sheet to a backing paper or another sheet positioned under the sheet and wind the resultant sheet. CONSTITUTION:The first prepreg sheet is fed with the first delivery device 1 and cut for each prescribed length at an angle (theta) between the cutting direction and the fiber direction with a cutter 6. The cut first prepreg sheet is then contact bonded to a backing paper 3 or the second prepreg sheet fed with the second delivery device 2 using a contact bonding and peeling means 5. A release paper 8 of the first prepreg sheet is simultaneously peeled. The peeled release paper is subsequently wound by the first winder (1a). The backing paper 3 and the second prepreg sheet, together with the first prepreg sheet, are wound by the second winder (2a).
