BIOMIMETIC LIGHT WEIGHT COMPOSITE STRUCTUREWITH HONEYCOMB-TRABECULA

In order to develop light-weight biomimetic composites , the microst ructure of A1 dichotoma was investigated in detail. A three dimensional honeycomb-columniation model was proposed and several design concept s forfurther development of three dimensional composite st ructure were discussed. At the same time , the advantages andapplication possibility were described. The result s show that there is an integrity network-columniation st ructure inthe whole fore wings of A1 dichotoma. This network st ructure is made of air sacs , and although it present s theirregularity and diversification , it is almost similar to the honeycomb-shaped polygon st ructure.
