Numerical analysis of natural fibre composite for marine structures

Abstract

In general, traditional shipbuilding is done with steel and later shifted to an aluminium combination for weight reduction. In naval vessels replacing steel with a composite Mast will reduce the magnetic signature when compared to steel [1]. By looking into the current environmental situation, the development of a "Green Composite or Hybrid Composite" is required. The objective of this paper is to suggest a natural fibre / hybrid composite that suits a marine structure such as a ship. Using classical laminate analysis, the natural fibre which is to be reinforced with Kevlar is studied based on the laminate properties. Pre-designed general cargo ship's selected structure is replaced with the steel-hybrid composite shows a reduced lightship weight.
