Impact Resistance of Composite Laminates Manufactured by New z-Pinning Technique

새로운 z-피닝 기술로 제작된 복합적층판의 내충격 특성

  • Published : 2009.07.01

Abstract

In this paper, conventional z-pinning technology which can be used to reinforce inter-laminar property of laminated composites is introduced and new z-pinning technique recently proposed by author is also introduced. On some trial specimens manufactured by the new z-pinning technique, the low-velocity impact test was performed and impact damage area was measured. Similar impact test was performed on normal composite laminate specimens and those test results were compared to each other. Consequently, it can be seen that the new z-pinning technique is more useful in applying to mass production of z-pinned composite laminate structures than the conventional techniques and some clear improvement on impact resistance of z-pinned composite laminates manufactured by the new z-pinning technique is observed.

본 논문에서는 복합적층판의 취약한 층간 특성을 보강할 수 있는 z-피닝 기술에 대하여 기존에 알려진 방법들을 소개하고, 최근 저자에 의하여 제안된 새로운 방법을 소개하였다. 새로운 방법을 적용하여 시제작된 z-피닝 시편들에 대하여 충격시험을 수행하고, 충격손상 영역을 측정하였다. z-피닝 기술이 적용되지 않은 일반 복합재 시편에 대해서도 동일한 시험을 수행하고, 두 결과를 서로 비교하였다. 결과적으로 새로운 z-피닝 기술은 기존의 기술에 비하여 양산에 적용하기가 매우 유리한 장점이 있으며, 새로운 z-피닝 기술이 적용된 복합적층판 시편들의 내충격 특성이 확실히 향상되고 있음을 알 수 있었다.
