An octogrid structure and method of forming the same for a composite laminate structure is provided. The octogrid sub-structure comprises: a first ply layer comprising a plurality of first elongate tapes oriented in a first direction and a plurality of second elongate tapes oriented in a second direction; and a second ply layer comprising a plurality of third elongate tapes oriented in the first direction and a plurality of fourth elongate tapes oriented in the second direction, the second ply layer being overlaid atop the first ply layer. A first end of each of the elongate tapes is positioned approximately adjacent a midpoint of an adjacently positioned one of the elongate tapes; and a second and opposing end of each of elongate tapes extends freely beyond a central grid portion defined by a length of a portion between the first end and the midpoint of the elongate tapes.
