Abstract

A method for estimating the strength of structural elements made of composite materials with a thermosetting matrix, which was characterized by the presence of exfoliation-like defects and process-induced deformations, was proposed. In order to determine the process-induced deformations, a mathematical model, which considered thermal and chemical deformations, heat release in the course of matrix polymerization, as well as changes in the matrix properties in transition from the superelastic to the solid state, was implemented. A modeling of the deformation of a standard blank with an interstitial exfoliation-like defect was carried out. A quantitative defect of the effect of the process-induced deformations and the initial dimensions of the defects on the load at which the defect begins to grow was made.
