Abstract: Plant based fibre composites may, in future, become materials to replace synthetic fibre polymer based composites and natural fibres owing to their attractive specific properties, low cost, simple processing technologies, eco-friendliness and ability to recycle after use. This thesis aims at introducing new natural fibres for use as fillers in a polymeric matrix, enabling production of cost effective, biodegradable and lightweight composites for load carrying structures. Agave (Agave Americana) leaf fibre, one such kind, is rich in cellulose, relatively inexpensive and abundantly available. In this study, extraction of Agave leaf fibre was carried out and investigations on its physical, chemical and mechanical properties were determined experimentally. The effect of alkali treatment of the fibre at varying concentrations, temperature and holding time were also studied. A Scanning electron microscopy (SEM) was used to analyse the morphology of raw and alkali treated fibres. The mechanical properties such as tensile, compressive, flexural, impact and water absorption test of the alkali treated continuous Agave fibr. Based on these studies, the following major conclusions have been arrived at: newline Agave fibre has better chemical properties, mechanical properties and surface orphology, and it is also found that alkali treatment improved all the properties newline The mechanical, water absorption and morphological properties of continuous Agave fibre reinforced epoxy composites are good and further alkali treatment enhanced all these properties. newline Optimum fibre length and alkali treatment of short Agave fibre improve the mechanical properties of composites prepared with the same. By hybridizing Agave fibre with glass fibre, more efficient composites can be prepared in terms of mechanical properties. The above observations facilitated a few fabrications, which may play as evidence for the best use of this aesthetic, ecofriendly and cost effective novel material in future.
