Deformation Studies of Polymer Matrix Composites Reinforced With Jute Fibre: A Continuum Modelling Approach

The present project work deals with the deformation studies of polymer matrix composites reinforced with jute fibres, utilizing continuum modelling approach.Jute Fibre reinforced polymer matrix composite consists of better mechanical properties such as high stiffness and high strength due to low density,corrosion resistance, electrical insulation,these advanced composites replaced the metals.The composite strength mainly depends upon volume/weight of reinforcement,Length/ diameter ratio of fibres,orientation angles and other aspects.In the current analysis using ANSYS simulation software designed a composite model with respective Jute fibre reinforcement polymer matrix,subjected it to longitudinal,transverse loading(Depends on Fibre orientation).From that investigated the mechanical properties and stress strain behaviour of composite material.Designed a Six ply composite(Jute 60 wt % + polymer 40 wt %)with and without crack,subjected it to three point bending test,from that analysed the deformed shape of the body,stress-strain distribution at each layer,and calculated flexural stress and strain,von misses yield criterion,maximum shear stress theory,simulation results are giving more accurate after comparing with literature values.And also calculated stress intensity factor(Mode I)for six ply jute fibre reinforced polymer composite with introducing a crack,analysed that stress intensity factor by variation of crack length and applied stress
