Abstract : Notched and unnotched instrumented Charpy impact data and tensile, flexural, compressive and shear property data of multi-angle and hybrid graphite reinforced epoxy resin composites are presented from the perspective of property trade-off studies. Two Modulite 5206 basic graphite fiber orientations are evaluated; composites in which the filament repeating unit direction is 1) 0 degrees, and 2) 0 degrees, + 45 degrees, -45 degrees and 90 degrees. The hybrid configurations are fabricated using the basic graphite orientations with discrete amounts of supplementary third phase fibers (glass, Nomex, and PRD-49 Type III) interspersed in the composites in 0 degree and in -45 degree and + 45 degree directions.
