Study on the Manufacturing Method of the Biomimetic Drag Reducing Morphology Replication Mold
In order to manufacture the drag reducing morphology replication mold used for biomimetic drag reducing film fabrication, the real shark skin and micro riblets machined with ultrasonic elliptical vibration cutting (UEVC) were used as templates respectively, followed by the casting process. The manufacturing process and the morphology quality of the molds was studied, and the biomimetic drag reducing effect and suitable application field was analyzed. The result indicates that: the bio-replicated forming mold based on shark skin is superior in morphology similarity with the real shark skin; the UEVC mold can achieve simplified riblets with high quality, and is feasible for large area mold manufacture and riblets spacing adjustment. The riblets morphology made with UEVC has wider application field than the shark shin morphology because of its flexibility of spacing adjustment.
