The present work involves manufacturing of long fibre reinforced thermoplastic composites by single stage using polypropylene as matrix material and continuous sisal fibre roving as reinforcement and Maleic Anhydride Polypropylene (MAPP) as a coupling agent. The continuous Sisal fibre roving were obtained from external source and Physical properties were studied. Chemical treatment of fibre has been done using NaoH and Nacl solution to remove lignin content results in better adhesion observed between matrix and fibre. Extrusion process has carried out by introducing compounding element and screw configuration by that fibre attrition has been reduced. Special type of screw elements was used to convey the fibres into the extruder. Test plates were obtained for different screw speeds with different volume fraction. Microscopic tests and Solvent test were also conducted in order to do fibre length analysis, obtained Test plates were tested as per ASTM standards. Improved Mechanical properties were obtained and the result values were correlated and validated with the fibre length and screw speed.
