Multiple face sheet isogrid structures

摘要

An isogrid structure formed from multiple face sheets (14) and multiple stringers (16). Each face sheet (14) and each stringer (16) being an individual component. Each stringer (16) having two or more joints for attachment to the face sheets (14). The face sheets (14) formed from flat sheet material and include a pattern of openings for attachment of the joints on the stringers (16). The geometry of the openings matching the geometry of the joints on the stringers (16). The assembled unit is formed by inserting each joint on a stringer (16) through its corresponding opening in a face sheet (14) and then bonding the joint to the face sheet (14).
