Abstract
Disclosed herein is a fiber optic rod having good mechanical properties (such as tensile strength and tensile modulus) and good water resistance and a process for producing the same. The fiber optic rod is formed by impregnating, followed by curing, a fibrous reinforcement with a resin composition composed of epoxy (meth)acrylate oligomer and xylene-formaldehyde resin, or epoxy (meth)acrylate oligomer and acid anhydride-modified epoxy (meth)acrylate (which is obtained by modifying epoxy (meth)acrylate oligomer with an organic acid intramolecular anhydride) as curable components and a reactive diluent of monofunctional and/or multifunctional (meth)acrylate and ultraviolet-sensitive polymerization initiator as essential components.
