The big problems for improving the performance of the airplane wing are reducing the threat of bird strike and improving aviation safety, by decreasing the weight, increasing the impact resistance, and keeping anti-icing and deicing of composite wing skin. In order to solve above problems, the principle of design and technology of bio-inspired composite wing skin based on the multi-region fiber structure and impact-resistant function of biology will be studied by this project. A series of research work can be conducted, such as the characterization and modeling of the structural parameters of the mantis shrimps feeding appendages and composite wing skin, the analysis of models and influence factors, the finding of the mapping rule between biological impact-resistant and mechanical impact-resistant. Furthermore, the building of the design principle, the manufacturing technology, the performance testing, and the application of the composite wing skin also will be carried out. As results, the scientific problems of the impact-resistant mechanism and functional rules of the mantis shrimps feeding appendages, the bionic design and engineering principle of composite wing skin will be clarified. In addition, the bio-inspired composite wing skin with scale-down also will be manufactured, in according with the performance of light weight, impact-resistant, anti-icing and deicing. This work can provide a novel design principles, new technologies and engineering methods for composite wing, which has important theoretical significance and practical application value.
