Abstract:
A method of constructing a bonded joint in a structure, comprising:forming a plurality of ribs in a surface of a first structural member to be bonded to a second structural member, said ribs in said first structural member extending along a portion of said first structural member in an area to be bonded to a corresponding area of said second structural member, said ribs projecting a uniform height in the range 0.15 mm to 0.25 mm above a first surface of said first structural member in the area to be bonded;forming in said first structural member a second surface between said ribs and the periphery of said first structural member in an area to be bonded to said second structural member defining an area near said periphery having a predetermined distance from the proximal ends of said ribs greater than the height of said ribs;applying sufficient uncured adhesive to the area between the first and second structural members to fill the area between the ribs when the ribs are in contact with the second structural member and to extend said adhesive to the edge of the first structural member to thereby cause a first predetermined uniform thickness of adhesive between the first and second structural members in the area of the ribs and a second predetermined thickness of adhesive in an area at the periphery of the first structural member in the area to be bonded, said second thickness of adhesive having a greatest thickness at least twice said first thickness of adhesive and said second thickness of adhesive being chosen to improve resistance of the adhesive to peeling of the periphery of the area to be bonded;fastening said first structural member to said second structural member by a plurality of fasteners after application of said adhesive to hold said structural members in alignment during curing of said adhesive; and curing said adhesive.
