摘要： The present invention relates to cellulose nanofibers that have good dispersibility in water and can be contained in a water-soluble polymer at high concentration, and to a method for obtaining the cellulose nanofibers. The present invention further relates to a fiber reinforced composite material using the cellulose nanofibers. Cellulose nanofibers having an average degree of polymerization of 100 or more and 800 or less and an aspect ratio of 150 or more and 2000 or less are produced by subjecting unmodified cellulose to an enzyme and/or acid treatment, and to a mechanical shearing treatment. The cellulose nanofibers have good dispersibility and can be dispersed in a water-soluble polymer at high concentration, and therefore a fiber reinforced composite material having high strength can be obtained.

摘要： The present invention provides a glass fabric excellent in strength and modulus of elasticity, and a glass fiber sheet material using the same. The glass fabric is obtained by weaving glass yarns produced by bundling the glass fibers of 3 to 6 pm in fiber diameter, spun from a molten glass prepared by melting a glass composition as a raw material for the glass fibers. The glass fibers have a composition wherein the content of SiO2 is 57.0 to 63.0% by mass, the content of Al2O3 is 19.0 to 23.0% by mass, the content of MgO is 10.0 to 15.0% by mass and the content of CaO is 5.5 to 11.0% by mass, based on the total amount of the glass fibers, and the ratio of the content of MgO to the content of CaO, MgO/CaO falls within a range from 0.8 to 2.0.
