Abstract
An all fiberglass decking panel has been designed to the requirements of the trilateral code for military bridging and the circular of requirements for new construction strategic sealift ships. The truss structure provides a lightweight fiber reinforced plastic (FRP) module that can be rapidly installed as decking for floating structures or military causeways. The edge supported composite deck can span up to 3 m×9 m at a weight less than 100 kg/m 2 (20 lb/ft 2). Triangular elements are fabricated using a single, thick ply of 3D-braided fiberglass textile drawn through a pultrusion die. The triangular pultrusions are bonded together with face sheets, using Plexus adhesive, to form the deck modules. The assembly is optimum weight for a plate over a span because the triangles carry the load with truss action and the face sheets carry the load in beam (EI) bending.
