Abstract: A localized fiber reinforcement places strong tensile strength fibers across a hypothetical split line near notches in beams to curtail split propagation caused by cross-grain tension that may otherwise significantly reduce the strength of a beam used as a spanning member. An adhesive coated patch may be applied after a notch is cut in the beam or fibers may be attached to a beam at a factory near the location of an anticipated notching.

Keywords: fiber reinforcement, tensile strength fibers, wooden structure members, beam, adhesive, fiber patch
