Tensile and Buckling Analysis of the Polymer Composite Beam Reinforced by Natural Jute Fiber

This research focuses on the preparation of polymer matrix composite material by (hand lay – UP) method, where the material was prepared from unsaturated polyester resin (up) as a matrix reinforced by natural jute fiber with different volume fractions (3%, 4%, 5%, 6%).The experimental work and finite element techniques were used to analysis the tensile and the buckling analysis of the composite beam reinforced by natural jute fiber at different volume fraction. The results of experimental work of the modulus of elasticity were in the range of the theoretical results. The critical load increased with increase the fiber volume fraction that ( cr P =610N) at ( f V = 3%) and ( cr P =830N) at ( f V =6 %) for the experimental results.While ( cr P =619N) at ( f V = 3%) and ( cr P =877N) at ( f V =6 %) for the finite element results
