This document summarizes the design and analysis of using a composite material for the outer link of a roller conveyor chain. It begins with an introduction to roller conveyor chains and their applications. It then describes the design process for the original outer link made of carbon steel, including hand calculations to determine the link dimensions. Finite element analysis was conducted on both the original design and a modified design using glass fiber-epoxy composite material. The results showed that the composite material link weighed less and experienced lower stresses than the original design, indicating that using a composite material can improve the design of the chain outer link.
