Development of Engineering Data on Advanced Composite Materials
Abstract
Engineering data have been generated on six advanced composite materials; T300/AFR800 (graphite/epoxy); SiC/5506 (silicon carbide/epoxy; HyE 2034D (pitch based graphite/epoxy); T300/V378A (graphite/polyimide); HyE 1076J (graphite/epoxy); and 6535-1 (graphite/epoxy). 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.
