一方向ガラス繊維によりラッピングを施したGFRP板ダブルストラップ継手の引張性能に関する研究

抄録

The use of adhesive bonding is to be a key in realizing longer spans and larger sizes of FRP structures. Then, this study focuses on a strengthening technique using a wrapping single layer of glass fiber by Vacuum Infusion molding technique over conventional double strap joints of GFRP plates. The strengthening effects of the technique on the tensile performance of the joint are investigated through tensile experiments. The experimental results indicated that the VI wrapping technique increases the loading capacity of the joint and FEM analysis revealed that the one effectively reduces the shear and normal stresses in the adhesive at the edge of the connecting plates.
