For this purpose, three types of laminates were prepared on a polypropylene matrix, a styrene-butadiene-styrene copolymer and an epoxy resin. The laminates were coated with a polyurea resin. The coating was applied with a special hot spray device, because of the strongly reactive precursors. The pull off strength needed to destroy the examined joints was compared and the macroscopic analysis of damage caused by the hit impactor with the energy of 19.6 J was performed. Impact damage and the structure of layered composites were subjected to microscopic analysis.
