Abstract
In order to apply composite materials fabricated by filament winding for a shock absorber under impact loading, their toughness should be improved. To overcome the problem, it is necessary to develop the configuration suitable for the object. The ring shape made by filament winding with some of notches along the internal circumference was investigated in this paper to increase the toughness by delamination effect under the equivalent value of impact load. The analytical results developed in this paper considering the propagation of stress waves were verified by the experimental results.
