A method of splicing together a first composite core and a second composite core, the method comprising:
- positioning of the first composite core adjacent to the second composite core, the first composite core and the second composite core each having a plurality of enclosed cell members extending between an upper surface network and a lower surface network, the first composite core and the second composite core each also having a plurality of flanges that are unenclosed extensions of the plurality of enclosed cell members, the plurality of flanges extend between the upper surface network and the lower surface network, wherein the positioning the first composite core adjacent to the second composite core includes overlapping the first flange and the second flange so as to define bond surfaces on the first flange and the second flange as the portions on the first flange and the second flange that overlap;
- applying an adhesive to at least one of the bond surfaces of the first flange and the and the second flange;
- and
- locating a first magnet adjacent to the first flange and locating a second member adjacent to the second flange, the first magnet and the second member being located opposite to the bond surfaces of the first flange and the second flange, the first magnet and the second member positioned to provide a pressure on the adhesive as the first magnet and the second member are magnetically attracted to each other.

A method of splicing together a first composite core and a second composite core, the method comprising:
- positioning the first composite core adjacent to the second composite core, the first composite core and the second composite core each having a plurality of enclosed cell members extending between an upper surface network and a lower surface network, wherein the positioning the first composite core adjacent to the second composite core includes abutting a first plurality of outer cell walls of the plurality of enclosed cells of the first composite core adjacent to a second plurality of outer cell walls of the plurality of enclosed cells of the second composite core so as to define bond surfaces therebetween;
- applying an adhesive to a least one bond surface formed by the adjacent first plurality of outer cell walls of the plurality of enclosed cells of the first composite core and the second plurality of outer cell walls of the plurality of enclosed cells of the second composite core;
- locating a first magnet on an interior surface of the first plurality of outer cell walls of the plurality of enclosed cells of the first composite core and locating a second member on an interior surface of the second plurality of outer cell walls of the plurality of enclosed cells of the second composite core, the first magnet and the second member positioned to provide a pressure on the adhesive as the first magnet and the second member are magnetically attracted to each other.
