Natural fibres are emerging as a strong alternative to synthetic materials in prosthetic development, offering enhanced durability, sustainability, and cost efficiency. A recent study involving Professor Dr. Tezara Cionita from INTI International University’s Faculty of Engineering and Quantity Surveying examined how natural fibres could replace conventional materials in below-knee prosthetic sockets.
Professor Dr Tezara Cionita’s research highlights how natural fibres such as hemp, flax, jute, sisal, banana fibre, and kenaf can replace synthetic materials in below-knee prosthetics.
Traditionally, prosthetic sockets are made from synthetic materials such as carbon fibre and plastics. While these materials are durable, they are often heavy, rigid, and expensive. The study found that fibres such as hemp, flax, jute, sisal, banana fibre, and kenaf offer key advantages, including high impact resistance, a superior strength-to-weight ratio, improved biocompatibility, and significant environmental benefits.
Prof. Tezara noted that prosthetic users frequently struggle with the weight and rigidity of current sockets. “Natural fibre composites offer a lighter alternative without compromising durability, which is crucial for long-term users who rely on prosthetics for mobility and daily life,” she explained.
The study also explored various natural fibre combinations and discovered that hybrids like hemp-flax composites provided greater strength and flexibility. However, challenges remained, particularly in water absorption, which could degrade the material over time. Prof. Tezara acknowledged this limitation but pointed to promising solutions. “Advanced surface treatments and hybridisation—combining natural fibres with synthetic reinforcements—can improve resistance and longevity. We’re also exploring resin modifications to enhance bonding and reduce moisture retention. This ensures that natural fibres maintain their eco-friendly nature while meeting the durability requirements of daily use,” she said.
The study indicated that hybridised natural fibre composites could significantly lower production costs, making high-quality prosthetics more accessible, particularly in developing countries where affordability remained a significant barrier. Prof. Tezara stated that integrating natural and synthetic fibres could lead to strong, lightweight, and cost-effective sockets. “This could be a game-changer, especially in developing countries where affordability is a major barrier,” she added.
The research was part of a collaborative effort involving universities from Malaysia and Indonesia, demonstrating a regional commitment to advancing sustainable prosthetic technology. Beyond material innovation, the study also considered the long-term impact on amputees, aiming to enhance comfort, affordability, and accessibility.
“This isn’t just about creating a product,” Prof. Tezara emphasised. “It’s about improving lives. A more comfortable, affordable, and sustainable socket means greater mobility and independence for amputees. That’s the ultimate goal.”
With continued research and development, natural fibre composites could redefine prosthetic socket manufacturing, offering a sustainable alternative that does not compromise strength or function.
Ongoing research and development could position natural fibre composites as the new gold standard in prosthetic socket manufacturing, improving accessibility and quality of life for amputees worldwide.
