Fractography of Composites.
Abstract
The purpose of this program was to begin the development of a fractography handbook for composite materials. The fractured samples were examined to identify and document the different fractographic features associated with different loading conditions, materials and fiber orientations. The first group of samples consisted of graphite/epoxy (T300/AFR 800) and graphite/bismaleimide (T300/v378A). The types of loading examined were tension, compression, flexure, fatigue and interlaminar shear in orientations of 0, 90, and 45 at room temperature. Some tests included edge delamination in tension and Mode I type samples with both graphite/epoxy and graphite/PEEK materials. Some samples were moisture conditioned by placing each one in a high humidity (100%) environment at 160 F until the approximate saturation level was reached. In addition to conducting R.T. tests with samples conditioned at 50% and 100% saturation levels, some tests were conducted at 260 F after being moisture conditioned. Some fatigue tests were conducted on graphite/PEEK samples in various orientations. Keywords: Failure analysis, Fibers, Tension, Compression, Flexure, Mechanical behavior.
