  • Method of installing a grommet in a wall of composite material
    Patent number: 5083363
    Abstract: The present invention provides a method of installing a grommet within an opening in a wall of composite material. An opening (10) is formed in a wall of composite material (12). A countersink (20) is formed at one end of the opening (10). A grommet (22) is placed into the opening (10). A split sleeve (28) is placed on the small diameter portion (30) of a mandrel (32) which is attached to a power puller (36). The mandrel (32) with the split sleeve (28) is placed through the opening (10) and a grommet (22). The power puller (36) is then operated to pull the mandrel (32) back through the opening (10) and the grommet (22) thereby expanding the split sleeve (28) which in turn provides for the radial expansion of the grommet (22). During the radial expansion of the grommet (22), ends of fibers (16) are forced into the surface of the grommet (24 ). After the mandrel (32) has been pulled all the way through the split sleeve (28) both it and the split sleeve (28) are removed from the grommet (22).
