摘要：
A molded article excellent in dynamic characteristics and water degradation resistance can be obtained by using a fiber-reinforced polypropylene resin composition including a carbodiimide-modified polyolefin (a), a polypropylene resin (b) and reinforcing fibers (c), wherein the content of the carbodiimide group contained in a resin component in the fiber-reinforced polypropylene resin composition is 0.0005 to 140 mmol based on 100 g of a matrix resin component, and the reinforcing fibers (c) are sizing-treated with a polyfunctional compound (s); and a molding material using the fiber-reinforced polypropylene resin composition.
