Abstract

Aspen fiber/polypropylene composites were made using several different levels of aspen fiber (0 to 60% by weight) with and without the addition of a compatibilizer (maleic anhydride grafted polypropylene, MAPP). These composites were tested under various relative humidity conditions and in water soaking, boiling water, cyclic liquid water and oven drying tests. In all moisture test conditions, as the level of fiber increased in the composites, the rate and extent of moisture sorption increased as compared to pure polypropylene. The presence of MAPP in the composites, in general, decreased the extent of moisture pickup in all of the tests.
