A composite panel comprising:
- a first skin;
- a second skin;
- a core between the first skin and the second skin;
- a plurality of reinforcing pins, with a first end of the reinforcing pins being connected to the first skin at a first connection point, and a second end of the reinforcing pins being connected to the second skin at a second connection point;
