Title:
GLASS FIBERS FOR RESIN REINFORCEMENT USE AND GLASS FIBER-REINFORCED RESIN MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2023/007948
Kind Code:
A1
Abstract:
Provided are glass fibers for resin reinforcement use, which have excellent processability and enables the production of a fiber-reinforced resin molded article having excellent mechanical properties. The glass fibers for resin reinforcement use comprise glass fibers and an organic substance adhered onto the surfaces of the glass fibers, in which the nitrogen content N in the organic substance is 0.010 to 0.600% by mass relative to the whole amount of the glass fibers for resin reinforcement use, the carbon content C in the organic substance is 0.120 to 1.500% by mass relative to the whole amount of the glass fibers for resin reinforcement use, the ignition loss L of the glass fibers for resin reinforcement use is 0.200 to 2.000% by mass, and the N, the C and the L satisfy formula (1). (1): 0.220 ≤ (N×C)1/2/L ≤ 0.405
