abstract The paper compares the influence of the type and number of composite reinforcement layers on the impact resistance, as well as the effect of the matrix type. Carbon, aramid and carbon-aramid fabrics were tested, and block copolymer styrene-butadiene-styrene and epoxy resin were also tested. In addition to impact tests, investigations were also carried out on the adhesion of the coatings, without reinforcement and with one layer of fabric, to the steel substrate. The highest values of pulloff strength were obtained for the coatings based on the SBS copolymer reinforced with fabrics. In the case of the coatings reinforced with aramid and aramid-carbon fabric, both adhesive and cohesive damage occurred during the pull-off test.
