Study on the micro-replication precision of shark skin

The biomimetic highly-efficient drag reduction surface can be directly replicated by shark skin as biological template, and the pre cured micro-embossing technology is put forward aiming at the thermosetting materials. In the process of bio-replicated forming, the replication precision is one of the most important factors in evaluating the forming effect, and the convincing and reliable assessing method has become an urgent problem to be solved. In this paper, the new evaluating way on the basis of statistical method is put into application, which provide the new idea and method to study the forming quality and effect, and the replication-precision of single scale and regional scales is in comprehensive and deep analysis. In addition, the factors causing forming errors are also illustrated and discussed, which lay the foundation for further research.
