Claims14
A composite panel comprising:
- a first panel skin;
- a second panel skin;
- a core arranged between the first panel skin and the second panel skin;
- wherein the core is bonded to the first panel skin and the second panel skin;
- the composite panel further comprising a two-part insert comprising:
- a first insert piece;
- and a second insert piece;
- wherein the core defines a cavity extending between the first panel skin and the second panel skin;
- wherein the first insert piece is arranged within the cavity and at least partially enclosed by the core, the first panel skin and the second panel skin;
- wherein a first face of the first insert piece is bonded to the first panel skin, and a second face of the first insert piece is bonded to the second panel skin;
- wherein the first insert piece defines a bore extending from the first face in a direction towards the second face;
- wherein the first panel skin defines a through-aperture corresponding to the position of the bore;
- wherein the second insert piece is arranged in the bore and attached to the first insert piece;
- and
- wherein the second insert piece defines a threaded hole for receiving a fastener.

A method of manufacturing a composite panel comprising:
- locating a first insert piece in a cavity in a core of a composite panel, the cavity extending through the core;
- positioning a first panel skin and a second panel skin either side of the core;
- curing the first panel skin and the second panel skin so as to:
- bond the core to the first panel skin and the second panel skin;
- bond a first face of the first insert piece to the first panel skin;
- and
- bond a second face of the first insert piece to the second panel skin;
- the method further comprising:
- forming a through-aperture in the first panel skin corresponding to the position of a bore in the first insert piece, the bore extending from the first face in a direction towards the second face;
- and
- attaching a second insert piece to the bore;
- wherein attaching the second insert piece to the bore comprises accessing the bore via the through-aperture;
- and
- wherein the second insert piece defines a threaded hole for receiving a fastener.
