| dc.description.abstract | Netkaná textilie z druhotných surovin využívaná firmou Ideal vykazovala nedostatky při lisování a konečném aplikaci v automobilovém průmyslu. Problémy byly způsobeny lisováním vlhkých nebo dokonce mokrých materiálů po transportu mezi výrobcem a odběratelem. Z původních materiálů byly připraveny menší vzorky (30x30 mm). Nejprve byl zkoumán prostup tepla skrze netkanou textilii pomocí specializovaného zařízení poskytující základní údaje o tepelné vodivosti materiálu. Následně byla vysušená textilie stanovena jako referenční a došlo k navlhčení ostatních vzorků přidáním vody o 10, 20, 30% (hmot.). Připravené vzorky byly následně ohřívány pomocí hydraulického lisu a za studena lisovány v druhém lisovacím zařízení. Mechanické vlastnosti lisovaných materiálů byly následně testovaný pomocí trhací zkoušky a trojbodového ohybu. Posledním měřením bylo zaznamenání ohřáté netkané textilie a vliv vlhkosti na chladnutí netkané textilie. | cs |
| dc.description.abstract | The recycled non-woven material which was brought from the Ideal company, had problems while molding and using it for the end use applications in automobile sector. The problems were the materials were wet, while receiving and had very weak mechanical properties. Firstly, the heat transfer of the material was studied in our lab with the help of thermal conductivity measuring instrument, this experiment is done to get a basic idea about the thermal conductivity of the material. And, with this material, we planned to make samples with four different moistures level 0%,10%,20%,30% respectively. The samples were prepared at the dimensions of (30*30) mm, so that it could be molded and studied in our lab in suitable conditions. Then, each samples were prepared individually based on their respective moisture levels, water percentage that should be added was also calculated based on their different moisture percentage level and added, then the sample was packed in the air tight covers and kept in the room temperature for 2 days in our lab. Then all the samples were pressed in hot pressing machine, and in cold press for molding. After the material is molded the samples were prepared from it in appropriate dimensions for 3-point bending test and tensile test to study about the mechanical behavior of this material. We also carried out the thermal analysis of the material to find out which samples with different moisture levels have faster rate of heat dissipation immediately after pressing is done. | en |
