Mechanical Properties Investigation of Natural Polymers

The paper presents a methodology of tests of mechanical properties of natural polymers. Aging test of polymers in an atmosphere of high humidity by using the climate chamber was discussed. The effect of humidity value changes on the degree of compaction was researched for different degrees of humidity. Next part of the paper presents the results of determination of friction coefficient of agglomerated natural polymers. The values of friction coefficient were calculated for different values of polymer temperature. The temperature values were similar to the values of temperature for polymer during agglomeration process.
