A caution flag is being given by the University of British Columbia’s Okanagan School of Engineering to manufacturers who incorporate fibers such as flax, hemp, cellulose nanofiber, and kenaf in a drive for greener solutions. In collaboration with MIT and the National Research Council of Canada, a team of researchers from the Composites Research Network and the Department of Biology have been studying the development and application of bio-sourced composites, in particular flax and hemp fibers. Their research found that when raw natural fibers are exposed to high humidity, mold growth was present. The researchers are now warning manufacturers that this mold growth could potentially lead to early deterioration and structural failure.
