摘要： PROBLEM TO BE SOLVED: To provide a fiber/resin composite material having excellent transparency, high strength, light weight, a very low coefficient of thermal expansion, high elasticity, and a very large fracture energy (fracture strain).
SOLUTION: The fiber/resin composite material is prepared by impregnating a nanofiber sheet with a noncrystalline synthetic resin. The noncrystalline synthetic resin has a parallel light transmittance ≥70% in a thickness of 50 μm. The nanofiber sheet has a Young's modulus at least 9 times higher than that of the noncrystalline synthetic resin. Since the composite material is a product of impregnation between the nanofiber sheet and the noncrystalline synthetic resin excellent in light transmittance, it has high transparency. Since the composite material is one between the nanofiber sheet and the resin, it has light weight, high strength, and high elasticity. By compositing the nanofiber sheet and the noncrystalline resin greatly differing from each other in Young's modulus, it is possible to realize a material being high in modulus (Young's modulus), having a very low coefficient of thermal expansion close to that of the nanofiber, and being transparent.

摘要： PROBLEM TO BE SOLVED: To provide a fiber-reinforced composite material in which high transparency can be always maintained without no influence of temperature conditions or wavelengths, and to which various functionalities are given by a composite of the fibers and the matrix material. SOLUTION: A fiber-reinforced composite material comprising fibers having an average fiber diameter of 4 to 200 nm, and a matrix material, and 60% or above of light transmittance of a wavelength of 400 to 700 nm in 50 μm of thickness. Due to the fiber having an average fiber diameter smaller than the wavelength of a visual light (380 to 800 nm), little refraction of the visible light by the fibers may be generated, and further, scattering loss of the visible light at the interface between the fibers and the matrix material cannot easily occur even when the temperature or wavelength is changed. Therefore, high transparency of a visible transmittance of 60% or above in 50 μm of thickness can be stably maintained. COPYRIGHT: (C)2010,JPO&INPIT
