Glass fiber composite material composition having improved impact strength
Disclosed is a glass fiber composite material composition having further improved compatibility between glass fibers and polypropylene and thus maximized interfacial adhesion between the resin and the glass fibers in a glass fiber composite material. The present invention provides a glass fiber composite material composition comprising: (A) 60-93% by weight of polypropylene; (B) 1-30% by weight of glass fiber sized with a silane-based compound; and (C) 1-10% by weight of a polypropylene resin modified with maleic anhydride and a methacryloxysilane-based compound.
