Optical bodies, for example optical films, are formed with inorganic fibers embedded within a polymer matrix. In some embodiments, the refractive indices of the inorganic fibers and the polymer matrix are matched. There need be no bonding agent between the fibers and the polymer matrix. The inorganic...http://www.google.fr/patents/US20060257678?utm_source=gb-gplus-shareBrevet US20060257678 - Fiber reinforced optical films
