The scope of this research emphasises the understanding of the micro response and microstructural changes in cellulosic fibres when subjected to monotonic or cyclic loading. Moreover, the concern with producing environmentally friendly products (for instance, packaging materials) has provided the impetus to investigate novel materials. Specifically, we wish to ascertain the suitability of biodegradable nanocomposites, as in bacterial cellulose polyhydroxybutyrate (PHB) nanocomposites as high-performance load-bearing multi-component systems. The outcome of such work would have tremendous impact on the polymer, packaging, textile and paper making industries insofar as being able to efficiently and effectively utilise natural materials in the production of (novel and old) products through environmentally sustainable industrial processes. This research seeks to establish rigorous physical models for the mechanical response of cellulosic fibres, networks and nanocomposites. These models are intended to address, and bridge the gap between, the micro-, meso- and macro-scales through the development of suitable material parameters. Furthermore, the primary concern of this research project is to evaluate the suitability and applicability of novel materials, viz, biodegradable nanocomposites, to create high-performance mats and tissues. The successful development and understanding of the micromechanical behaviour of such materials come at a crucial time when a prudent and efficient coupling of materials research and ecological concern need be placed. Very little, or almost no, research has been conducted on developing and understanding the 'enhanced' mechanical response of such materials. Several advantages may accrue from using cellulose as reinforcing fibres in nanocomposites: cellulosic fibres are a natural, cheap source; moreover, their mechanical properties are superior to those of other existing synthetic fibres.
