The aim of this work is investigation of plastic and glass-plastic composites contact resistance. Mechanical characteristics of the studied composite materials were determined. Some regularities of their decomposition at contact loading were established. Limiting values of contact force depending on indentation depth for two different indenter forms and four different indenter diameters were calculated. FE calculation was performed allowing determining the strained condition around the contact zone as well as destruction zone size. The study demonstrates a possibility of use of composite general durability characteristics for damage predicting at a low-speed impact.
