Abstract : This report describes mechanical property data collected in support of a fan blade analysis model. The development of the blade model is part of a foreign object damage (FOD) study of jet engine fan blades. Use of the properties in the model allows one to evaluate potential fan blade materials. Part A of this report contains a discussion of the mechanical property tests conducted on two metallic materials: 410 stainless steel and 8A1-1Mo-1V titanium. These two materials were selected because of their use in the J-79 blade and F-101 blade, respectively. Part B of the report contains a discussion of mechanical property tests conducted on the two composite components of a hybrid composite blade: boron/2024 aluminum and stainless steel wire mesh/2024 Aluminum. These two composites are used in the hybrid composite APSI blade. Quasi-static tensile tests and torsional tests were conducted on unidirectional specimens for the two composites indicated above.
