Abstract

From the observation of biological structure, it was found that the fiber changes its density and direction continuously when passing around a hole. Some experiments have demonstrated that the mechanical properties of this kind of structure were much better than those of a structure containing drilled or punched holes. An iteration method was proposed for the design of pre formed hole structure of a single ply. Then the mechanical property of the laminates consisting of this kind of ply was analyzed. Calculation showed that the obtained laminates have higher load carrying capability than the conventional ones.
