Mechanical characterization of composite pipe systems joined using different radii pipes subject to internal pressure

OpenAlex İngilizce

Failure tests for internal pressurized composite pipe system joined by using different radii pipes were carried out by the finite element method and experimental tests. The composite pipes were produced from E glass fiber/epoxy. DP410 and DP490 type adhesives were used to join the composite pipes. The numerical results and experimental results were compared. It was shown that the numerical analyzes results were close to experimental results. Tangential, radial, axial, and shear stress values on composite pipes and adhesive layers were obtained via numerical analyses in the radial direction. Additionally, the von Mises stress distributions were obtained on the adhesive. The effects of adhesive layer lengths, adhesives types, and orientation angle on the effect of the joint zone were investigated.
