Title : Physical, chemical and mechanical characterization of Natural Bark Fibres (NBFs) reinforced polymer composites
Fibers extracted from bark, which are normally by-products if not waste from other sectors using bark, especially to extract chemicals, or discard it, are receiving massive attention in the last few years. Therefore, chemical composition (cellulose, hemicellulose, and lignin content), thermal degradation, and mechanical characterization studies are increasingly carried out, also in view of their potential application as short random fibers in polymer composites. This study aims at reviewing the current state of studies, trying to elicit which bark fibers might be most promising amongst the potentially enormous number of these. These could be tested for the purpose of further use, also in competition with other expressly produced fibers not from bark, in the production of composites.
