Mechanical Characterization of Water Hyacinth Fiber Reinforce Epoxy Composite Under Tensile and Flexural loading using water hyacinth (Eichhornia crassipes) as reinforcement and epoxy resin as the matrix material. The composite was fabricated using the hand lay-up technique, which is a simple and cost-effective method suitable for laboratory-scale production. The fiber extraction process involved collection, cleaning, drying, and manual separation to obtain usable fibers.
A fiber-to-matrix ratio of 30:70 (by weight) was selected to achieve a balance between strength and workability. The epoxy resin and hardener were mixed in a 2:1 ratio to ensure proper curing and bonding. The fabricated composite specimens were prepared according to ASTM standards (D3039 for tensile testing and D790 for flexural testing) to ensure reliable and standardized results.
Mechanical testing was carried out at IIT Kanpur to evaluate tensile and flexural properties. The tensile test results of Sample 1 exhibited higher tensile strength (6.91 MPa), greater strain, and better energy absorption compared to Sample 2 (3.48 MPa), indicating superior ductile behavior. The stress–strain curves also showed zig-zag patterns due to non-uniform fiber distribution, porosity, and micro-crack formation.
In Flexural Test, the flexural strength for both the specimen is 28MPa indicate the uniformity in fabrication and consistency in material composition. However flexural modulus indicate stiffer and resist. Sample 1 demonstrates higher strain at failure indication better ductility.
The results demonstrate that water hyacinth fiber can be effectively utilized as a reinforcement material in polymer composites. This study highlights the potential of converting an invasive aquatic plant into a value-added engineering material, contributing to sustainability and environmental management.
