A method of manufacturing a net edge composite core, the method comprising:
- wrapping a plurality of full size mandrels with a composite material to form wrapped full size mandrels;
- wrapping a plurality of partial mandrels with the composite material to form wrapped partial mandrels;
- assembling the wrapped full size mandrels and the wrapped partial mandrels;
- curing the wrapped full size mandrels and the wrapped partial mandrels in a tool;
- and
- removing full size mandrels and the partial mandrels.
