© Experimental Stress Analysis - 56th International Scientific Conference, EAN 2018 - Conference Proceedings. All rights reserved. The reduction of emissions and using natural materials are the current trends. One of the ways how to reduce emissions is the vehicles weight reduction. The requirement on the weight reduction is also applied to car seats cushions. Polyurethane foam is still the most often used material for cushion of car seats. The weight saving could be achieved by manufacturing and using composite polyurethane foams with lower density and improved mechanical properties provided by the fibres reinforcement. Samples of polyurethane foam with coconut fibers were made and their inner structure was scanned by means of an electron microscope (SEM). Beside the static properties for the car parts (seats) it is important to know especially the dynamic properties. Therefore, the samples were tested on the dynamic mechanical analyzer (DMA). The chosen method was compression with constant strain, sweeping frequencies and various temperatures. This way, the storage and loss modulus of the reinforced foam samples were determined. The significant dependency of those main elastic constants on the using of reinforcement and also the varying ambient temperature has been found.
