Repair of Composite Structure Using Cold Sleeve with Polymer Filling Material

Abstract:

This paper describes the failure analysis of a cold sleeve using modified adhesive layer of polymer Protegol. The tensile test was carried out to estimate material properties of the polymer and the two-parameter Mooney-Rivlin constitutive model was used. An axisymmetric FEM model with additional plane symmetry was developed for simulation of cold sleeve. Cohesive zone material failure modeling uses contact elements to model interface delamination. The bilinear behaviour of sleeve material with normal tractions and separation distances and material nonlinearities together with contact were considered. Commercial finite element software ANSYS was utilized to carry out the static nonlinear analysis.
