Abstract

The problem on the formation of stress fields in a pipeline with a repair composite band during the solidification of the polymer resin is considered. Heating of the composite material due to the heat release during the polymerization reaction is modeled. Two-dimensional pictures of location of the glass transition front during cooling are obtained. A numerical analysis of the stress state of a fragment of the pipeline and the composite band during the cooling process is performed. The effect of matrix shrinkage during its glass transition on the level of the technological stresses is analyzed.
