Abstract

When new manufacturing techniques, materials, and socket designs are introduced, prosthetic limb consumers may need them since the corpus of knowledge currently available for safe fabrication may no longer be relevant. In this paper, the authors investigated the influence of dynamic and cyclic loading on the resulting damage and its propagation in natural fiber–reinforced polymeric composites utilized in trans-tibial prosthetic sockets experimentally, numerically, and theoretically. Using epoxy as the matrix and reinforcements such as perlon, rami, coir, pineapple, glass, and carbon, six groups were formed using vacuum pressure. The materials used in the socket above underwent tensile and fatigue testing. Using a finite element method, the theoretical section calculated the failure index, fatigue life, volume fraction, and theoretical safety factor. The experimental findings allowed us to assess fracture mechanisms during this loading. In addition to the viscoelastic properties, the kind of reinforcement significantly influences the observed parameters. This study thoroughly examined the criteria for natural fiber–reinforced polymer composites for prosthesis purposes, emphasizing efficiency, structural performance, environmental effects, financial considerations, and safety factors. The suggested natural fiber–reinforced (NFR) composites are a practical and environmentally beneficial alternative since they satisfy safety and performance requirements. NFR composites are positioned to significantly influence how biomedical engineering is produced in the future as sustainability becomes a major design and production priority.

Lay Summary

Amputees have yet to utilize prosthetic sockets composed of natural fibers, despite their potential to be created from traditional sources. This study successfully designed and evaluated a new prosthetic socket that employs biocompatible and sustainable components to lower the prosthesis's weight and associated expenses while retaining durability under cyclic loads.
