  • Composite shape forming structure for sealing and reinforcing concrete and method for making same
    Patent number: 5981050
    Abstract: A multiple ply composite structure used to reinforce, seal and shape concrete structures has a first ply formed of unidirected continuous filament reinforcements which are bonded together by a thermosetting polymeric resin matrix. A second ply comprises a plurality of separately spaced protuberances, each of which is individually coated with a hardenable thermosetting polymeric resin. The hardenable thermosetting polymeric resin of the second ply bonds the first ply to the second ply by forming a concave resin meniscus which anchors each of the protuberances of the second ply to the first ply.
