Abstract
A monocoque fiber reinforced plastic composite modular bridge structure and fabrication method are described in which, in a preferred embodiment, one or more bridge modules of selected length and cross-section are fabricated by applying composite fabric over a mandrel of substantially the intended shape of the module, enclosing the mandrel and composite in a vacuum bag, infusing the fabric with resin, preferably utilizing the vacuum assisted resin transfer molding process, allowing the resin and fabric to cure, and applying finishing operations to the module for installation at a bridge site.
