Method for adhesive bonding plug details for composite structures

摘要

An apparatus and method for repairing defects in composite materials using a tapered disk sized to fit the part being repaired. Also included is a bolt sized to fit through a central hole in the disk. A spring is positioned on the bolt with a washer. A nut is attached to the end of the bolt and tightened to place pressure on the washer to compress the biasing device. An adhesive is applied to the tapered disk prior to engaging the composite material. A threaded bushing is used to fixedly attach a second bolt completely in the hole.
