Abstract:

A series of mechanical tests was conducted on fiber glass-epoxy laminates. The loadings used were uniaxial tension biaxial tension with principal-stress ratios of 12, 11, and 21 and pure shear. The most unique tests were those involving the biaxial loadings. These tests were carried out on a specially designed test fixture using a cable-pulley system in conjunction with a conventional universal testing machine. Data were obtained on the limit strength and apparent ultimate strength of flat laminates subjected to biaxial loading. Under biaxial loading, the parallel-ply lamination arrangement was found to be slightly superior to the cross-ply lamination arrangements. The shear tests were accomplished on thin-walled tubular specimens subjected to pure torsion.
