Abstract:
1. An ultralight unit load device, comprising: a broad composite base panel having first and second faces and a peripheral surface; an open-structured edge component extending along a substantial portion of said peripheral surface, said edge component comprising an upper longitudinal element and a lower longitudinal element both extending parallel to the base panel and spaced from each other, and two spaced apart transverse elements extending transversely to and connected to the longitudinal elements for defining a first chamber next to the composite base panel that extends along the edge component, the longitudinal elements being longer than said transverse elements, the edge component further comprising additional elements defining two additional chambers extending one after the other and next to the first chamber and being spaced from the base panel, the elements defining the chambers all being of lightweight material, said edge component including first and second spaced flanges substantially parallel to one another, said first and second flanges interconnected by a web to form a receiving area for mounting a marginal portion of said base panel, said edge component presenting a substantially flat top profile set flush with the said first and second faces of said base panel; attachments means for attaching said edge component to said marginal portion of said base panel; and a corner section component of lightweight material having fitted end protrusions for engaging said chambers of said edge component for absorbing shear forces.
