Long-fiber-reinforced resin composition and molded article thereof

A long-fiber-reinforced resin composition comprising component (A) and component (B), wherein:na content of the component (A) is 50 to 90 wt %;a content of the component (B) is 10 to 50 wt %;a content of reinforcing fiber comprised in the component (A) is 20 to 60 wt % relative to a total amount of long-fiber-reinforced resin composition;Component (A) is a long-fiber-reinforced thermoplastic resin pellet comprising a thermoplastic resin, a modified resin comprising polyolefin modified with an unsaturated carboxylic acid or a derivative of an unsaturated carboxylic acid, and a reinforcing fiber, and satisfying (A-1) to (A-4):n(A-1): a melt index of the thermoplastic resin at a resin temperature of 230° C. and a load of 21.18N, is 100 to 250 g/10 min;(A-2): a relaxation time λ of the thermoplastic resin at an angular frequency ω=1 (rad/sec) calculated from a storage modulus G′ and a loss modulus G″, measured with a cone-and-plate rheometer, is 0.02 to 0.05 (sec);(A-3) a content of the reinforcing fiber is 40 to 70 wt % of (A); and(A-4) a content of the modified resin is 1 to 5 wt % of (A); andComponent (B) is a resin comprising polyolefin satisfying (B-1) and (B-2):n(B-1) a melt index of the resin comprising polyolefin resin at a temperature of 230° C. and a load of 21.18N, is 20 to 70 g/10 min; and(B-2) a relaxation time λ of the resin at an angular frequency ω=1 (rad/sec) calculated from a storage modulus G′, and a loss modulus G″, measured with a cone-and-plate rheometer, is 0.23 (sec) or less.
