dc.description.abstract | 복잡한 형상의 구조 건전성 모니터링을 위해서는 높은 취성 등 기존 센서의 단점을 보완 할 수 있는 매우 유연하고 내구성이 확보된 센서가 필요하다. 본 연구에서는 전기활성고분자의 한 종류인 Polyvinylidene fluoride trifluoroethylene (PVDF-TrFE)를 사용하여 직물센서를 제작하였다. 또한 제작된 직물센서를 복잡한 형상을 가지는 탄소섬유/에폭시 복합재료 구조물에 적용하여 구조 건전성 모니터링을 위한 도구로써 활용 가능성을 평가하였다. 복합재료 구조물의 손상 반응과 파손 메커니즘을 분석하기 위해 다중간헐적 압축시험을 수행하였다. 시험 과정에서 복합재료 구조물에 삽입된 직물센서는 전기적 신호를 발생 (0.05 V-0.25 V)하며 실시간으로 균열발생과 균열위치를 감지해냈다. | - |
dc.description.abstract | For structural health monitoring of a complex shaped structure a new sensor that can compensate for the drawbacks of the current sensors such as brittleness is needed and the sensor should be highly flexible and durable. In this study a textile sensor made of polyvinylidene fluoride trifluoroethylene (PVDF-TrFE) which is a type of electroactive polymer was fabricated. And the textile sensors were applied to a complex shaped structure (an egg-box panel made of carbon/epoxy composite) for checking their feasibility of structural health monitoring. To correlate the collapse response with failure mechanisms of the structure the multiply-interrupted compressive test was carried out. During the test, the textile sensors succeeded to prove their applicability for damage detection (crack initiation) by generating electric voltages (0.05 V-0.25 V) in the real time. | - |
