  Since the beginning of its existence, the automotive industry has been recognized by the engineers as one of the main branches of the global industry due to the possibilities which may offered in respect of development of construction, technologies and materials. Willingness to obtain newer and better solutions in the field of construction and operation of car has induced a global race of the producers of vehicles. The increasing number of cars and a rise of the level of the ecological awareness was the reason for introduction of legal regulations aimed at the limitation of exhaust emission [1]. To adapt to the legal regulations, many new constructional and technological methods were introduced; they were intended to limit the mass of the vehicle and reduce the fuel consumption; to these ends, inter alia, light materials were used (aluminium alloys, composites and polymers). Reduction of the mass by 10% allows limiting the consumption of fuel by 5-7% [2].Polymers are the example of materials which have a wide application in car vehicles [2, 4, 5]. Fig. 1 shows the element of car which are manufactured with the application of various types of polymers, including those ones used in the studies, discussed in the present paper. Apart from the elements, presented in Fig. 1, there are many smaller or greater car parts, produced from other polymers such as PVC or ABS (acrylonitrile butadiene styrene) [2]. Polymer elements are often connected using gluing technology [6-8] because gluing allows, inter alia, joining different constructional elements with different physical properties [9]. Such necessity occurs during assembly of different car parts. Additionally, it is an effective method for connecting materials of such type due to aspect of joint tightness what, in the case of car, is very important [10]. Strength is one of the specific parameters of the adhesive joint. The value of adhesive joint is affected by many factors, clas[...]
