Fiber reinforced resin composition, molding material, and method for producing fiber reinforced resin composition

A fiber reinforced resin composition comprising:

• a melt-kneaded product (A) prepared by melt-kneading a first resin (A1) and a second resin with a reactive functional group (A2);
• a third resin (B);
• and
• a fibrous filler (C);
• wherein the first resin (A1) is at least one resin selected from the group consisting of polyamide, polyester, polyphenylene sulfide, polyacetal, styrene based resin, polyphenylene oxide, polycarbonate, polylactic acid, polypropylene, and polyethylene, and said third resin (B) is at least one thermoplastic resin selected from the group consisting of polyamide, polyester, polyphenylene sulfide, polyacetal, styrene based resin, polyphenylene oxide, polycarbonate, polylactic acid, polypropylene, and polyethylene;
• and
• 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 wtt, and 10 to 99.8 wt%, respectively, and form a resin composition while said fibrous filler (C) accounts for 0.1 to 300 parts by weight per 100 parts by weight of the 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, and
• wherein the particles of said component (A2) contain finer particles with a number average particle diameter of 1 to 100 nm comprising a compound resulting from the reaction of the component (A1) and the component (A2), the area occupied by said finer particles comprising the compound resulting from the reaction of components (A1) and (A2) accounting for 20% or more of that occupied by the particles of the second resin (A2).
