    Description

    The fungal resistance of high density polyethylene filled with 50% wood flour was investigated using laboratory soil block tests. Modifications to standard test methods were made to increase initial moisture content, increase exposure surface area, and track moisture content, mechanical properties, and weight loss over the exposure period. Mechanical properties decreased after 12 weeks exposure to Gloeophyllum trabeum and Trametes versicolor. However, irreversible damage due to water sorption made separating the effects of fungal attack and water sorption difficult. When compared on a dry basis, small weight reductions after fungal exposure suggest some attack by G. trabeum. Further modifications to test methodology are suggested.
