Analysis of the natural fiber reinforced polymer: Composite fiber rods (FRPCY)

Abstract

Fiber reinforced polymer composites (FRPC) can be used in new or repaired reinforced concrete structures. Fiber reinforced polymer composite yarn (FRPCY) can be formed as rods of different diameter and length to be used in the formation of concrete structures due to their superior light weight, corrosion resistance, the lack of material ductility and energy absorbing capabilities. The formation of these FRPCY rods using natural fibers yarns is tried in this work. Due to the variation of the fiber volume fraction of the yarn along its length, it will directly reflect on the fiber volume fraction of the formed composite. In this work, the relation between the yarn volume fraction and the composite fiber volume fraction were studied, taken into consideration its variation along the yarn length. The formation of these rods using flax yarns is tried in this work and their mechanical properties are investigated.
