Abstract : This report summarizes all of the research efforts required to complete the contract W56HZV-09-C-L550 (FY09). In addition, this report summarizes the material testing results of the contract W56HZV-08-C-0236 Work Directive(WD) 00017 (FY08). Both include the material testing of composite materials using the same testing procedures. Therefore, all material testing is considered as one combined project and this report summarizes all of the findings. FY08 included two materials and FY09 included six materials. The FY08 test plan was under a subcontract with Mississippi State University. Overall, there were four fiber/resin combinations tested: (1) Huntsman PolyUrethane (PU) Rencast 6405 with S2-Glass, (2) Applied Poleramic (API) SC-15 Epoxy with S2-Glass, (3) Applied Poleramic SC-15 Epoxy with S2-Glass and Fill with Aramid ZFibers, and (4) Huntsman PolyUrethane Rencast 6405 with Ductile Hybrid Fabric. The material properties include tensile elastic modulus, tensile strength, Poisson's ratio when the specimens are subjected to tensile loads, compressive elastic modulus, compressive strength, Poisson's ratio when the specimens are subjected to compressive load, shear modulus, and shear strength. All of these properties were measured with respect to all three material axes and therefore results include both in-plane (in the plane of the fibers) and out-of-plane properties. All material properties were measured at three test temperatures; (1) - 40 deg F, (2) 70 deg F, and (3) 140 deg F. Seven test types were used to determine the material properties. The testing procedures are discussed in detail in this report. The test types include; (1) in-plane tension, (2) in-plane compression, (3) in-plane shear, (4) out-of-plane tension, (5) out-of-plane compression, (6) out-of-plane shear, and (7) out-of-plane Poisson.
