In this collaborative project between Newcastle University and Universiti Malaysia Perlis (UniMAP), the team aimed to create a sustainable, cost-effective lower limb prosthetic socket (LLPS) using natural fiber-reinforced composites. The objectives included designing a green LLPS, assessing its environmental impact, and engaging stakeholders. PALF was selected as a sustainable reinforcement and incorporated into the composite. The design was guided by a static-friction (‘stiction’) load-transfer framework, developed previously by Goh and co-workers, which explains how force is transferred from the polymer to the fibres. The project has also inspired worldwide interest in sustainable LLPS development through a press release, receiving inquiries from students at Nanyang Technological University in Singapore and a group of 7th graders in the USA.
