The aim of this article is to investigate the characteristics of a composite fibre advanced materials used as a robotic link manipulator for replacement of rigid one. The composite material is combination of two and more fibre processed and bonded with epoxy, resulting hybrid form of material component with required properties which are to be analyzed for suitability with respect to its function, reliability, durability, safety and cost-effectiveness. The composites generally have high-strength, high-stiffness (graphite, kevlar, etc.) low-density (epoxy, polyvinyl) strong and stiff with lightweight. In this investigation, five different composite structural fibres are taken as a flexible link with joint flexibility for case study analysis. The rotating structural fibre link, loaded and tested different types of joint stiffness coefficients (kc). The numerical evaluations are conducted for structural fibre material for replacement rigid manipulator. The modeling of structural fibre single flexible link on the basis of Euler-Bernoulli beam theory and Lagrange’s equations of motion is studied and accurate modes of the system are obtained.
