Abstract
A method of cutting a wafer of composite core from a bulk composite core includes stabilizing the bulk composite core with a fixture, the bulk composite core having a plurality of tube members. The method also includes cutting through each of the tube members to create the wafer while the bulk composite core is stabilized by the fixture.

A method of cutting a wafer of composite core from a bulk composite core, the method comprising the steps of:
- providing a bulk composite core having a substantially hexagonal outer geometry and a plurality of tube members, each of the tube members comprises a plurality of reinforcement fibers disposed in a polymeric matrix;
- stabilizing the bulk composite core with a fixture having a hexagonal inner surface that lies adjacent to the hexagonal outer geometry of the bulk composite core;
- positioning the bulk composite core within the fixture so as to partially expose a desired amount of the bulk composite core for cutting;
- and
- cutting through each of the tube members in the bulk composite core to create a wafer having a substantially hexagonal outer geometry.
