OPTIMUM DESIGN IN THE STRUCTURES OF BEETLE FORE WINGS

In order to develop the light-weight biomimetics composite structures, two kinds of beetle fore wings beetles, Allomyrina dichotoma and Prosopocoilus inclinatus, were selected as the biomimetics objectives. Based on the microscope observation, the structure characterizations and the optimum design mentality in these two beetle fore wings were inspected. As a result: (1)Both beetle fore-wings are of sandwich plate structure with a central void layer, where there exist many distributed trabeculae. Thus the beetle fore wings are one of typical light-weight composite frame structures. (2)The structure of allomyrina dichotoma fore-wing is disposable and shows an economical design way, while the structure of prosopocoilus inclinatus shows a strong and durable design way.
