| Outline of Final Research Achievements |
To improve the adhesive strength, we performed surface modification of carbon fiber reinforced plastics (CFRP) using Nano-imprint lithography (NIL). Because a metal mold was used in the conventional process, the manufactured surface was limited to the 2.5 dimension. We propose an imprint process of three-dimensional shape with interlock structure using a soluble mold. We fabricated the soluble mold using negative photoresist by inclined exposure method, and investigated the fracture toughness of three-dimensional structures using DCB tests. As a result, it was found that the higher fracture toughness can be obtained by using imprint lithography compared with the conventional surface treatment using abrasive paper.
