fiber-reinforced resin composite body, and strengthening the matrix resin for fiber-reinforced resin

摘要

reinforcing fibers (A) and the fiber-reinforced resin containing a matrix resin (B) ( and C), a fiber-reinforced resin composite containing a reinforcing material (D) (E), reinforcing material (D) is, contains a cellulose nanofiber (F), the cellulose nanofiber (F) There, characterized in that it is obtained by refining the cellulose in defibration resin (G), and provides a fiber-reinforced resin composites and reinforced matrix resin for the fiber-reinforced resin. In addition, the cellulose nanofiber (F) is an after refining cellulose in defibration resin (G), modified cellulose nanofibers obtained by further reaction with a cyclic anhydride polybasic acid (J) (F1), to provide a fiber-reinforced resin composite.
