dc.description.abstractPultruded Jute Fibre Reinforced Unsaturated Polyester Composites (PJFRC) was prepared and examined stage by stage in this study. Three different fibre volume percent of PJFRC with 50, 60 and 70% were prepared using the pultrusion technique. The PJFRC with 70% of fibre volume percent was successfully produced and displayed a homogeneous fibre distribution before having a high attrition to the fibre surface if the fibre volume percent more than 70%. Analysis was done by means of mechanical analysis, dynamic mechanical analysis, thermal conductivity and thermal mechanical analysis. In every analysis, the unidirectional composite material was determined in the longitudinal and transverse fibre direction. Improvement in properties suggests effective stress transfer between fibre and matrix. Morphological assessment was done through micrograph observation in every mechanical testing evaluation. At 60% and 70% of jute fibre loading, tensile strength improved by 0.06% and 0.03% respectively, while the modulus of elasticity improved at 60 and 70% with 0.01% and 0.08% respectively. Increasing of fibre volume percent is said to improve the mechanical and physical properties of the PJFRC specimens. All of these parameters were then used for further analysis using finite element analysis. The finite element analysis program was used in order to estimate the coefficient of the thermal expansion at two different directions (longitudinal and transverse). Considering symmetry of the composite using the square array in representative unit cell, it was modeled for the Finite Element (FE) analysis using ANSYS software.en_US
