위그선 탄소섬유 및 폼 샌드위치 구조의 본딩 강도 특성 평가

초록

This study evaluates the bonding strength characteristics of carbon fiber–foam sandwich structures for application in Wing-In-Ground(WIG) craft. Sandwich panel specimens were fabricated using low-temperature curing carbon fiber prepreg and PVC foam cores. The specimens were manufactured through a vacuum oven molding process to produce composite sandwich panels. To investigate the structural performance and interfacial bonding characteristics between the face sheet and the core, flexural tests and drum peel tests were conducted. The flexural tests were performed to evaluate the structural stiffness and failure behavior of the sandwich structure, while the drum peel tests were used to assess the adhesive bonding strength between the carbon fiber skin and the foam core. Based on the experimental results, the interfacial bonding behavior and failure characteristics of the carbon fiber–foam sandwich structures were analyzed. The results of this study are expected to provide fundamental data for the structural design and bonding performance evaluation of composite sandwich structures for WIG craft applications.
