In this study, an effect of heat treatment to tensile properties for JFRPP (Jute Fiber Reinforced PolyPropylene) was examined. Specimens were made of heated plain woven jute cloth and Polypropylene. Heat treatment temperature to jute fibers was set in the range from 50℃ to 200℃. Treatment time was 1h or 5h. The result indicates that tensile strength of JFRPP using jute fiber heated from 110℃ to 120℃ for 1h was improved about 6%. However, Degradation of jute fibers begins to progresses by heating for 5h. Heat treatment temperatures of this case were relatively lower which are around 110℃. Plastic properties for JFRPP were also examined. Stress-strain curves of JFRPP under tension cyclic loading were drawn. Tensile strength of JFRPP subjected tension cyclic loading decreased for accumulated damage.
