Abstract
A composite structure that includes a plurality of components coupled together forming a joint, wherein the plurality of components are oriented such that a gap is defined at least partially therebetween. The composite structure also includes a filler structure positioned in the gap. The filler structure includes a honeycomb core including side walls that define a plurality of core cells, and an amount of resin within each of the plurality of core cells. The honeycomb core side walls facilitate restricting crack propagation in the resin from spreading between adjacent pairs of the plurality of core cells.
