Pultrusion of thermoplastic composites by natural continuous jute -study of density and tensile properties round prepregs-

In this paper manufacturing process and mechanical properties has been investigated in Pultrusion process using natural jute fiber HDPE and starch. Pultrusion process has been used for manufacture of wire shape prepregs. Natural jute fiber has been impregnated in impregnation die using extruder. The results show tensile strength has been decreased up to 19% in wire shape prepregs that produced using three impregnated pin in comparison to no pin. Also tensile strength of wire shape prepregs that has been produced using HDPE are 31% higher than wire shape prepregs with starch matrix. By increasing number of jute up to 3 fibers¡ Tensile strength has been increased up to multiple 2.. Impregnation of wire shape prepreg with starch matrix shows less jute impregnation than HDPE matrix. So that Jute has been exposure on one side and starch has been exposure other side and jute has been exposure symmetric in the HDPE matrix.
