Abstract: A void filler (14, 16) especially suited for filling large volumes is made from first and second panels (18, 20), each panel having a core (26) sandwiched between face sheets (22, 24). The core is typically a corrugated honeycomb core so that the panel is stiff, strong and yet lightweight. The panels each have generally horizontal upper and lower edges (30, 32) and generally vertical first and second (34, 36) edges. The panels are connected at a hinge (44) along their upper edges. A limiter (50), attached at or near the lower edges, limits the movement of the lower edges away from one another so the panels can move from a flat, storage condition to a use condition, exhibiting a generally inverted V-shape. Two void fillers can be hingedly connected to form an M-shaped void filler assembly (2).
