1. A delamination resistant fiber reinforced resin composite comprising:

  • a fiber reinforced resin composite panel formed of a lay-up of fiber plies and a resin matrix;

    at least one elongate fiber reinforced resin composite reinforcing member formed of a lay-up of fiber plies and a resin matrix; and

    a high shear strength, high toughness, thermosetting resin adhesive layer consisting essentially of a thermosetting resin located between juxtaposed surfaces of said fiber reinforced resin composite panel and said fiber reinforced composite reinforcing member for bonding said fiber reinforced resin composite panel to said fiber reinforced resin composite reinforcing member, said thermosetting resin having a higher shear strength and being different from the resin used to form said resin matrix of said fiber reinforced resin composite panel and said fiber reinforced resin composite reinforcing member, said thermosetting resin substantially entirely filling the space between said fiber reinforced resin composite panel and said fiber reinforced composite reinforcing member.
