Abstract

In this paper a new concept on z-pinning technology named by authors as 'z-pinning patch' will be introduced, which advantage is easy application at manufacturing site of composite structures. Using the trial manufactured z-pinning patch, the z-pinned composite single-lap shear joint specimens were successfully manufactured and tested to check the improvement of joint strengths. The z-pin's material is stainless steel and its surface was machined as zagged shape and chemically corroded to improve joint force with composite materials.

본 논문에서는 복합재 구조물의 제작 현장에서 쉽게 적용할 수 있는 장점을 갖는, 저자에 의하여 'Z-피닝 패치'로 명명된 새로운 Z-피닝 기술에 대하여 소개하였다. 시제작된 'Z-피닝 패치'를 사용하여 Z-핀이 박힌 복합재 단일-겹침 전단 접합시편을 성공적으로 제작하였고, 접합강도의 향상을 점검하기 위하여 시험을 수행하였다. Z-핀의 재질은 스테인레스 강이며, 복합재료와의 접합력을 향상시키기 위하여 Z-핀의 표면은 요철 형상으로 가공하였으며, 화학적으로 부식시켰다.
