ABSTRACT:
A grating comprising preformed fiber reinforced resin strips stacked in the positions of the intersecting bars of the grating and with the strips interleaving at the points of intersection, the reinforcement strips being embedded in a resin matrix. The method for making the grating comprises forcing the fiber reinforced strips with the fibers under tension, and assembling such preformed strips in a mold having a network of intersecting cavities for defining the grating bars, the cavities being initally charged with liquid hardenable resin material, so that the reinforcement strips are submerged in the liquid resin during assembly, the embedment resin being subsequently hardened.
