| Abstract | ||||
| Double-notch and shod-beam shear test supports have been designed and manufactured to measure the interlaminar shear strength of cross-ply composite laminate with different off-axis angles. A cross-ply [O019O0], glasslpolyester laminate was manufactured using hand lay-up technique. The laminate was cut at different off-axis angles (OD, 15', 3O0and 45') to give ([Oo/9O"]2,, [15°/-750]b, [30°/-60°]&, [45°1-450]d stacking sequences. In double-notch shear (DNS) test, the effect of shear length on interlaminar shear strength was investigated. In shortbeam shear (SBS) test, the effect of specimen width on apparent interlaminar shear strength was studied. The interlaminar shear stress distribution for both DNS and SBS specimens were obtained. Failure modes of DNS and SBS specimens were investigated. | ||||
