Properties of polymer composite reinforcement test under axial loading are described in the article. It is significant, that standart testing machine holding jaws crumple samples. In according to requirements of GOST 32492, it´s necessary to use a special muff, which was tested in the experiment. Creeping of material in steel tube was found out. Improved muff was suggested. Strength and deformation properties of glass-plastic reinforcement were determined. Technical solutions of muffs and jaws were also considered.
polymer composite reinforcement, rod, anchoring cover, test muff, adhesion, ultimate loading.
