PRODUCTION OF FRP MOLDED OBJECT

PROBLEM TO BE SOLVED: To obtain an FRP molded object reduced in voids and excellent in lightweight properties by using a prepreg with low resin content. SOLUTION: An FRP molded object is produced by laminating prepregs A wherein at least resin content is 15-27wt.% and the release resistance with a r...

Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an FRP molded object reduced in voids and excellent in lightweight properties by using a prepreg with low resin content. SOLUTION: An FRP molded object is produced by laminating prepregs A wherein at least resin content is 15-27wt.% and the release resistance with a release sheet is 40-250g/25mm or the prepregs A and prepregs B wherein resin content is above 27wt.% and a reinforcing fiber basis wt. is 50g/m or less so that the directions of reinforcing fibers cross each other and molding the resulting laminate so that the lowering of resin content by resin flow becomes 0.2wt.% or less as a whole.
