Evaluation of coconut coir fiber/groundnut shell reinforced epoxy composites for (Below-the-Ankle) SYMES prosthetic socket fabrication: tensile strength and performance analysis

This study investigates the tensile strength and mechanical performance of coconut coir fiber and peanut shell reinforced epoxy composites for use in prosthetic socket fabrication. The challenge addressed is the need for low-cost, durable, and lightweight materials for prosthetics, which are crucial for enhancing the quality of life for amputees, particularly in developing regions. The composites were fabricated with varying reinforcement ratios and subjected to tensile strength testing, with results indicating a significant variation in force at peak and elongation among the different formulations. Notably, the control sample exhibited the highest tensile strength (20.42 MPa), while the samples reinforced with coir fiber and peanut shells showed a range of strengths, suggesting potential for optimizing composite formulations for specific prosthetic applications. This research contributes to the growing body of knowledge on sustainable materials in medical device manufacturing, offering insights into the development of cost-effective and locally available materials for prosthetic sockets. Ultimately, the findings support national efforts to improve healthcare accessibility and promote self-reliance in prosthetic technology.
