CRACK GROWTH ANALYSIS OF THE INTERFACE FUNCTIONALIZED WITH NANOIMPRINT LITHOGRAPHY

摘要

In this study, microstructures are fabricated on adhesive area of carbon fiber reinforced plastic (CFRP) with surface modification using Nanoimprint lithography (NIL). Since this NIL-based technique is conducted during a curing process of composites, it reduces the time required and costs involved in conventional techniques such as sand blasting or plasma etching. FE analysis is performed to analyze crack growth in the interface and optimum size and shape of microstructures are investigated.
