Abstract:

In this work, composite materials for car seat covers composed of woven fabric + polyurethane foam (PU) + knitted fabric were tested by separation of components of the composite force, which are thermally connected with three different process speeds (30, 34 and 39 m/min) and two thickness PU (2 mm and 4 mm). The thermal bonding of the components into a composite is leading to reduction in thickness and weight of the composite compared to the amount of components before the joining. The force separation decreased as the speed for all samples increased. The smaller thickness of PU had an effect on the larger separation forces of composite components as well as higher abrasion damage. The purpose of this work was to investigate the influence of the thermal bonding speed of the composite components, the effect of PU thickness on the separation force, and abrasion properties.
