摘要： The present invention provides a fiber-reinforced resin composite as a fiber-reinforced resin composite (E) including a fiber-reinforced resin (C), which contains a reinforcing fiber (A) and a matrix resin (B), and a reinforcing material (D), in which the reinforcing material (D) contains a cellulose nanofiber (F), and the cellulose nanofiber (F) is obtained by micronizing cellulose in a fibrillated resin (G), and provides a reinforced matrix resin for the fiber-reinforced resin. The present invention also provides a fiber-reinforced resin composite in which the cellulose nanofiber (F) is a modified cellulose nanofiber (F1) that is obtained by micronizing cellulose in the fibrillated resin (G) and then reacting the cellulose with a cyclic polybasic acid anhydride (J).

摘要： The invention provides a thermoplastic resin composition, a molded article, and production methods therefor. The thermoplastic resin composition can sufficiently exhibit a cellulose addition effect and impart excellent mechanical strength to the molded article, particularly a foam molded article. More specifically, the invention provides a resin composition and a foam molded article thereof. The resin composition contains: a cellulose fiber (A); an amorphous resin (B) having a glass transition temperature of 160° C. or lower; a crystalline resin (C) having a melting point (melting peak temperature) of 80° C. to 150° C. and a melting start temperature lower than the melting point by 30° C. or more; and a thermoplastic resin (D) having a melting point or a glass transition temperature higher than the melting point of the crystalline resin (C) by 5° C. or more.
