Abstract:

Desirability of various test techniques for fiber reinforced composite materials is discussed from a stress analysis standpoint. Methods considered include tension tests, flexure tests, short beam shear, solid torsion rod, rail shear, and tubular specimens. Results show a tubular specimen provides the most unified procedure for complete characterization of a composite material. Tensile tests on orthotropic symmetric laminates are also shown to be useful. Flexure tests, while not desirable for precise characterization, seem useful for quality control purposes for 0 degree or 90 degree unidirectional specimens and bidirectional laminates. Author-PL
