Mechanical properties of Carbon-matrix composites for a blade runner’s artificial leg

Abstract

The use of fiber-reinforced polymer (FRP) for prosthetic devices is now very common. Various polymer resins have been reinforced the fiber yielding composite with better strength-to-weight characteristics compared to a single material and also providing better biocompatibility. The purpose of the present study was to examine a single glass, carbon fiber with various matrix combinations for a composite of a blade runner's artificial leg. The polymer matrices, namely epoxy bakelite (ER), casting (CR), orthocryl (OR), and polyester (PR) resins were selected, while evaluations of mechanical and physical properties of composite samples

Assessment of a Carbon Fiber Prosthetic Running Blade for Enhanced Reliability

“…Volume 25 (2023), Issue 4 carbon fiber (6,21,33). Different materials can be used in the manufacturing of prosthetic running blades include, including carbon fiber composites, thermoplastic polyethylene epoxy, and Vinylester, and some metal alloys such as high-grade aluminum alloy, steel, and titanium alloy (6,7,10,12,25,29). Carbon fiber prosthetic running blades offer several benefits and advantages over durability and reliability.…”

“…The study analyzed different blade designs and composite materials using finite element analysis. Ismail et al (10) reported the different combinations of glass and carbon fibers with various polymer matrices (epoxy bakelite, casting, orthocryl, and polyester resins) can be used for a blade runner's artificial leg. They suggested that the combination of the fiberorthocryl resin provided the best composite with the highest average tensile strength.…”
