    摘要： Although a microfibrillated cellulose has been conventionally added to a resin molded article for the purpose of improving the properties of resin such as strength, it is only possible to achieve the same level of strength as that of the resin itself. The object is to provide a resin molded article of greater strength. A molded article can be produced by blending resin with a microfibrillated cellulose having a type-II crystalline structure produced by treating a microfibrillated cellulose with an alkali solution. The molded article can be largely increased in tensile strength or flexural strength, tensile strain at break or flexural strain at break, and fracture toughness (work-of-fracture) compared to a molded article produced with resin containing a conventional microfibrillated cellulose.

    摘要： Disclosed is a highly transparent fiber-reinforced composite material including an assembly of cellulose fibers of 4 to 200 nm average fiber diameter impregnated with a matrix material so as to not only remedy the moisture absorbency attributed to cellulose fibers but also further improve transparency. There is provided a fiber-reinforced composite material including an assembly of cellulose fibers impregnated with a matrix material. In the fiber-reinforced composite material, hydroxyl groups of cellulose fibers are chemically modified through a reaction with one or more chemical modifiers selected from the group consisting of an acid, an alcohol, a halogenating reagent, an acid anhydride, and an isocyanate so that the ratio of a functional group introduced by the chemical modification is 5 to 40 percent by mole based on the hydroxyl groups of cellulose fibers before the chemical modification. The chemical modification of hydroxyl groups of cellulose fibers can reduce the hydrophilicity of cellulose fibers to thereby reduce the moisture absorbency of fiber-reinforced composite material. Further, the affinity between cellulose fibers and matrix material can be enhanced to thereby further improve transparency.
