Abstract

A method of cutting a wafer of composite core from a bulk composite core including the steps of placing the bulk composite core in a container, the bulk composite core having a plurality of tube members; depositing a potting compound in contact with an outer surface of the bulk composite core; curing the potting compound; and after curing of the potting compound, cutting through each of the tube members. A method of cutting a wafer of composite core from a bulk composite core, the method comprising the steps of stabilizing the bulk composite core by wrapping an exterior of the bulk composite core with a composite wrap, the bulk composite core having a plurality of tube members; curing the composite wrap; and cutting through each of the tube members.

Claims (4)

1. A method of cutting a wafer of composite core from a bulk composite core, the method comprising the steps of:

supporting the bulk composite core, the bulk composite core having a plurality of tube members; and

cutting through certain tube members from within each tube member with a circular saw by first cutting an interior tube member, then cutting within other tube members sequentially along a cutting path;

wherein the cutting path is a spiral cutting path that progresses from an interior tube member to an exterior tube member while skipping certain prescribed cell members.
