Ethiopia has abundant invasive aquatic plants like water hyacinth and water lily. Large masses of these invasive plants have a negative impact on the country’s water bodies, specifically at Lake Tana in Ethiopia, by infesting and deteriorating water quality and reducing the quantity of water. In this research work, an attempt was made to fabricate a natural fiber reinforced composite in which water lily fiber was used as the reinforcing material in a polyester resin matrix. Chopped water lily fiber reinforced polyester resin composites were prepared by varying the fiber content - 20, 40 and 60 wt.%. Mechanical properties such as tensile strength and flexural strength were tested as per ASTM standards to evaluate the influence of the fiber contents. The experimental results show that an increase in the fiber content enhanced the mechanical properties of the water lily fiber reinforced polyester composite. It was found that the composite with 40 wt.% fiber exhibited superior strength which could be suitably used for different applications.

In the field of composite materials there is growing emphasis on environmental impacts, resulting in the replacement of synthetic-based components with bio-based components, and in particular, attention to the production process. The focus of the paper is the production of a composite reinforced with natural fibers, which can find applications in the construction field as the reinforcement of wooden structural elements, or as a skin for boards or sandwich panels. In this sector, it is not necessary to achieve very high mechanical performance as in the automotive sector. On the other hand, the cost of the product must be kept low and the production process simple. The proposed composite was prepared with an epoxy resin matrix reinforced with a bidirectional woven fabric made of hemp fibres without any heat treatment. The composites were hand laminated and manufactured by cold moulding to reduce energy consumption. To optimize the behaviour of the composite, various specimens were manufactured, and factors such as the curing pressure, quantity of resin and layer orientation were modified. Tensile strength tests were conducted on specimens according to the ASTM D3039 standard.
