A vast majority of components are deformed after assembly. The aim of this study is to determine the influence of deformation under tension on hardness, friction and wear of PA6, PTFE and PE-HD. In terms of all examined plastics, reduction of hardness is observed (up to 38%) for deformed specimens. Moreover, this phenomenon is observed even during the initial stage of deformation (up to ϵ = 2,5% for PE-HD and PA6; ϵ = 1,25% for PTFE). Deformation (tension) affected wear in terms of all examined thermoplastics. Wear gets larger as a specimen is more deformed. In terms of coefficient of friction only PA6 appeared to be sensitive to deformation (value changed up to 10%). Deformation affects properties of PA6, PTFE and PE-HD. This fact ought to be consider during designing components made of this thermoplastics and analysing material behaviour and failure reasons. Moreover, changes occur during the initial stage of deformation (up to ϵ = 2,5% for PE-HD and PA6; ϵ = 1,25% for PTFE). As it appears, deformation through tension causes increase in wear.
