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.

Method for adhesive bonding plug details for composite structures

A method of manufacturing a carbon composite duct assembly includes providing a first carbon composite fabric layer having a first section. The first section is formed into a first portion and a second portion. The first portion is separately moveable relative to the second portion. The first portion overlaps the second portion to define a first corner of the first carbon composite fabric layer. The first carbon composite fabric layer is formed into at least a portion of a duct extending along an axis.

Composite duct assembly

A carbon composite duct assembly has a duct body having an opening. The duct body extends along an axis. The opening extends transversely to the axis. The duct body has a carbon composite fabric layer. The duct body has an axial flange extending along the axis and a peripheral flange extending along the opening. The axial flange and the peripheral flange overlap forming a corner of the carbon composite fabric layer.
