Abstract:
1. A method of making posts and kerfs in an interdigital bonded composite, the method comprising: determining desired spacing criteria for a plurality of posts and kerfs in a pair of slabs, as well as desired widths W of the posts and desired widths K of the kerfs which are larger than the widths W of the posts; wherein the posts in a first slab in the pair are configured to be received into corresponding kerfs in a second slab in the pair and vice versa, so that the pair of slabs can be interdigitated to assemble a composite in which there is at least one gap between each post in its corresponding kerf of a desired width; and creating at least one of an alignment post and an alignment kerf, in at least one of the slabs which is configured to cause the size of the at least one gap between each post in its corresponding kerf when the posts in the first slab are received into the corresponding kerfs in the second slab to be substantially the desired width; wherein the alignment post and the alignment kerf are configured to allow the plurality of posts and kerfs to be correctly aligned and positioned, in accordance with the desired alignment criteria and the desired widths.
