The load transfer in the structure around the notch is ensured by its rigidity which is ensured by the orientation of the fibers and thus the objective is to evaluate the value of the breaking load by the modification of the stiffness of the composite (stacking sequence). 0° 60° (a) 0° 60° (b) 0° 60° (c) Figure 7: (a) Load displacement curve under tension loading of simple geometry;(b) Load displacement curve under tension loading of modification1;(c) Load displacement curve under tension loading of modification 2.
