Abstract
The invention provides a fiber reinforced resin composition comprising a melt-kneaded product (A) prepared by melt-kneading a first resin (A1) and a second resin (A2) that has a reactive functional group as well as a third resin (B) and a fibrous filler (C), wherein, with respect to the contents of the components, the first resin (A1), the second resin with a reactive functional group (A2), and the third resin (B) account for 0.1 to 75 wt %, 0.1 to 15 wt %, and 10 to 99.8 wt %, respectively, to form a resin composition while said fibrous filler (C) accounts for 0.1 to 300 parts by weight per 100 parts by weight of said resin composition, said first resin (A1) and said third resin (B) forming a matrix resin, said second resin (A2) being dispersed as particles in said matrix resin, and said particles having a number average particle diameter of 10 to 1,000 nm. The invention relates to a fiber reinforced resin composition having rigidity and impact resistance in a good balance, a molding material, and a production method thereof.
