The automotive manufacturing represents one of the most developing segments of the engineering industry. The persisting tendency of designers to achieve the best technological level, car ́s safety level and also ecological running at keeping the low price level means necessity to still implement into own production new types of materials. Among these materials also belong so-called sandwich materials which combine steel sheets with the plastic core. These materials are used in the car design due to their lower weight and excellent acoustic properties. As a disadvantage of such materials there is lower temperature stability and worse technological processability. This paper deals with the evaluation temperature influence on the change of the sandwich material mechanical properties. For tests there were selected the characteristic mechanical tests for different loading types in light of the adhesive properties testing – the lap shear test and the T-peel test. The range of the testing temperature was from -40°C up to 80°C and was chosen with respect to the commonly used criterions for temperature resistivity of parts designed for the car-body design.
