초록

본 논문에서는 복합재 적층판의 고속충격 관통에너지를 예측하는 방법 중 하나인 정적압입 관통 실험을 수행하였다. 정적압입 관통 에너지를 정확히 분석하기 위해서 세 가지 방법을 이용하였다. 첫 번째로 AE 센서 신호 변화를 이용해서 압입 관통 지점을 판단하고 관통 에너지를 구하는 방법, 두 번째는 관통된 시편에 다시 관통실험을 수행하여 두 에너지 차를 이용해서 구하는 방법, 세 번째는 재수행한 관통실험의 하중-변위 그래프에서 최대하중지점을 압입 관통 지점으로 판단하고 에너지를 구하는 방법이다. 위 방법들에 의한 관통에너지 예측 결과를 제시하였고 고속충격 실험 결과와 비교하여 타당성을 검증하였다.

In this paper, static perforation tests are conducted to predict the penetration energy for the composite laminates subjected to high velocity impact. Three methods are used to analyze the perforation energy accurately. The first method is to select the perforation point using the AE sensor signal energy, the second method is to retest the tested specimen and use the difference between initial and retested perforation energy, and the third method is to select the perforation point based on the maximum loading point in the retested load-displacement curve of the tested specimen. The predicted perforation energy results are presented and verified by comparing with those by the high velocity tests.
