In this study, degree of carbonization and tensile properties of green composite using carbonized jute fiber (CJGC) were investigated. Before fabrication of CJGC, carbonization was conducted to the jute fibers in atmosphere.Carbonization temperatures were 300℃ and 400℃. Heating rates were 2℃/min and 60℃/min. Holding times were Ohr, 3hrs and 6hrs. CJGC was fabricated by using carbonized plain woven jute fiber and polylactic acid (PLA). The static tensile test was conducted. Crosshead speed was l.0mm/min. As a result, the young's modulus of CJGC(2℃/min) was improved in comparison with that of CJGC(60℃/min).The tensile strength of CJGC(400℃) was improved in comparison with that of CJGC(300℃). The young's modulus of CJGC(Ohr) was improved in comparison with that of CJGC(3hrs,6hrs). These results implied that carbonization temperature, heating rate and holding time affected the tensile properties of CJGC.
