Abstract

In a present era importance of FRP are steadily increasing due to its advantageous properties by enhancing mechanical properties of matrix by using fibers. Various researchers have worked for high strength fiber reinforces plastic as an attractive feasible material to replace metal and conventional materials. In last two decades the attempts are also made with natural fibers to replace conventional FRP, normally Glass and Polyester or Epoxy. Normally the rule of mixture can give reasonable results for predicting the end properties of FRP in longitudinal direction. However, for different fiber arrangement and length of fiber the loss in modulus is expected. Further, interfacial de-bonding, poor adhesion and voids also create loss in modulus of FRP. Hence, this research work is aimed to found the losses in modulus of FRP by considering natural fiber jute as a reinforcement and polyester as a matrix. The systematic experiments are carried out by using suitable molds and appropriate equipment. The attempts are made to study the effect of orientation of fibre is studied for modulus under longitudinal loading. Modulus property is simulated using standard FEA packages. The results obtained by 3D FEA analysis, theoretical models and experimental results for losses in modulus are following the same trend. The comparative assessment give the divergence of experimental results from available predictive model in term of modulus losses is the range of (0.16-75.06)% depending on various parameters.
