Innovative applications of woven fique-fiber epoxy biocomposites in eco-friendly product design

Abstract

Currently, different industries have shown interest in making their processes sustainable and environmentally responsible, which has turned biocomposite materials into a potential raw material to meet these expectations of sustainability and environmental responsability. Despite the emerging potential of biocomposites, its use in high-performance and innovative applications remains largely unexplored. This is the case of fique, Furcraea Andina, an indigenous plant in South America. This research proposes the manufacturability of natural fiber woven composites, specifically utilizing fique for Personal Mobility Vehicles (PMVs) as a case study for developing a furniture chair and a helmet. Firstly, a literature review and manufacturing tests were conducted to assess the impact of various manufacturing methods on the tensile properties of these composites, including vacuum bagging, hand lay-up, and resin infusion molding. This study integrates finite element analysis with experimental testing conducted according to the ASTM D3039 standard, FEM models aid to design the suitable layup stack-up and thickness. To enhance the properties of the material, a chemical modification process involving alkalinization with sodium hydroxide (NaOH) was done. Finally, it is reported that fique-reinforced biocomposites are suitable for both proposed applications and could be considered as an alternative to polymers or synthetic composites.
