Flexural Characteristics of Composite Deck Model Fabricated with VARTM

진공성형제작 복합소재 바닥판 모델의 휨특성분석

Recent days composite bridge deck is gaining attraction due to many advantages such as light weight, high strength, corrosion resistance, and high durability. In this study, composite sandwich deck models of hat, box, and triangular section type were fabricated by VARTM process. For those models, three point flexural test was carried out both in strong and weak axis. The experimental results are compared with each other to determine efficient section type. Also finite element analysis was performed to verify analysis model. It is demonstrated that the results of numerical analysis agree well with experimental results.
