Abstract:

Engineering data have been generated on six advanced composite materials T300AFR800 graphiteepoxy SiC5506 silicon carbideepoxy HyE 2034D pitch based graphiteepoxy T300V378A graphitepolyimide HyE 1076J graphiteepoxy and 6535-1 graphiteepoxy. Prepreg tape was obtained from each vendor and laminates and test specimens prepared. Five different static mechanical properties tension, compression, flexure, inplane shear, and interlaminar shear were measured on various fiber orientations at four different temperatures -67F, 72F, 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 160F and 100 percent relative humidity were conducted on each material and the effects on this exposure on several mechanical properties were determined. On four of the materials, tests were conducted on specimens with a hole located in the center of the gage section. On the last material, three different ply stacking sequences incorporating 0, 90, and or - 45 deg. piles were tested. These three different sequences gave rise to tensile, compressive, and zero stress in the thickness direction at the specimen free edges.
