Development of Engineering Data on Advanced Composite Materials

Abstract

Engineering data have been generated on four graphite reinforced advanced composite materials; SP313 (graphite/epoxy by 3M); AS/3004 (graphite/ polysulfone by Hercules); AS/4397 (graphite/polyimide by Hercules) and; T300/ F178 (graphite/polyimide by Hexcel). Prepreg tape was obtained form each vendor and laminates and test specimens prepared at UDRI. Five different static mechanical properties (tension, compression, flexure, inplane shear, and interlaminar shear) were measured on three fiber orientations (0, 90, and plus or minus 45) at four different temperatures (-67 F, 72 F, and two elevated temperatures). Tensile fatigue, creep, and stress-rupture tests were also conducted and four thermophysical properties (thermal expansion, thermal conductivity, specific heat, and glass transition temperature) were determined. Environmental agings (at 160 F and 100% R.H.) were conducted on each material and the effects of this exposure on several mechanical properties were determined.
