Title:
LONG FIBER-REINFORCED POLYAMIDE RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2009051885
Kind Code:
A
Abstract:

To provide a long fiber-reinforced polyamide resin material which is excellent in handling property and molding property with hardly causing falling-off of glass fibers from a pellet, and further has advantages as long fiber-reinforced material such as mechanical strength and heat resistance.

The long fiber-reinforced polyamide resin composition comprises (A) an aliphatic crystalline polyamide resin; (B) an amorphous polyamide resin and/or a semi-aromatic crystalline polyamide resin having Tc2 of 185C or lower; and (C) a glass long fiber. The aliphatic crystalline polyamide resin (A) has a melt mass flow rate (MFR: based on JIS K7210) of 70 g/10 min or more. The long fiber-reinforced polyamide resin composition preferably comprises 20-85 wt.% of the component (A), 1-25 wt.% of the component (B) and 20-75 wt.% of the component (C).
