This report presents the testing and behavioral study program leading to the development of structural design criteria for a fiberglass-reinforced-polyester (GRP) laminate. The Marine Corps is to employ GRP modules as reusable elements for rapid construction of temporary protection for military ground targets against conventional weapon threats. The objective of the test program was to determine and evaluate the mechanical characteristics of the GRP through a series of flexural, tensile, compressive, and shear tests. In addition, more efficient uses of the structural strength of the GRP were investigated whereby the GRP laminate sheets were employed as facings of sandwich plates. Because of its superior ballistic resistance, the GRP was selected for the Marine Corps protective construction program; however, the laminate is inherently weak in compression and is highly susceptible to creep, localized buckling, and moisture. The established criteria will provide design guidance for GRP structural components of protective structures.
