FUNDAMENTAL STUDY ON MECHANICAL PERFORMANCE OF CFRP STRUCTURAL MEMBER MOLDED BY VaRTM

Abstract

Although the number of FRP applications for civil structures has increased in recent years, the use of FRP in the architectural field remains limited. CFRP offers lightweight, high rigidity, and reasonable elasticity, with strength comparable to other structural materials. Therefore, CFRP has the potential to enable the construction of lightweight spatial structures. This study aims to clarify the mechanical characteristics of CFRP pipes manufactured by the VaRTM method using an outer mold. Mechanical testing at the material and component levels will be conducted, and the results are expected to contribute to the development of structural design.
