Abstract
Disclosed herein are a recycled polypropylene composite material resin composition and a washing machine including the same. A glass fiber-reinforced recycled polypropylene resin composition includes, in weight percent of the glass fiber-reinforced recycle polypropylene resin composition, about 10 to 30% of waste glass fiber mat-reinforced thermoplastic (GMT), about 35 to 47% of a homo-polypropylene base resin, about 30 to 45% of long glass fiber-reinforced polypropylene, and about 0.5 to 3.0% of a compatibilizer, and a weight average molecular weight of the composition may be about 250,000 g/mol or more.
