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