This study investigated the residual tensile properties of plain woven jute fiber reinforced poly(lactic acid) (PLA) during thermal cycling. Temperature ranges of thermal cycling tests were 35–45 °C and 35–55 °C. The maximum number of cycles was 103 cycles. The quasi-static tensile tests of jute fiber, PLA, and composite were conducted after thermal cycling tests. Thermal mechanical analyses of jute fiber and PLA were conducted after thermal cycling tests. Results led to the following conclusions. For temperatures of 35–45 °C, tensile strength of composite at 103 cycles decreased 10% compared to that of composite at 0 cycles. For temperatures of 35–55 °C, tensile strength and Young’s modulus of composite at 103 cycles decreased 15% and 10%, respectively, compared to that of composite at 0 cycles. Tensile properties and the coefficient of linear expansion of PLA and jute fiber remained almost unchanged after thermal cycling tests. From observation of a fracture surface, the length of fiber pull out in the fracture surface of composite at 103 cycles was longer than that of composite at 0 cycles. Therefore, tensile properties of the composite during thermal cycling were decreased, probably because of the decrease of interfacial adhesion between the fiber and resin.

Generally, interfacial adhesion between natural fiber and biodegradable resin can be improved by alkali treatment. The effect of alkali concentration of treatment on fatigue property of natural fiber as reinforcement should be examined to assure the use of structural material using green composite. The purpose of this study is to examine fatigue properties of 1% and 15% alkali treated natural fiber. Jute fiber was used as specimen. Alkali treatments were conducted in distilled water with NaOH 1% and 15%. X-ray diffraction measurement of alkali treated jute fiber was conducted. Fatigue tests and damage observations of non and alkali treated jute fibers were conducted. As a condition of fatigue test, the stress ratio was 0.1 and the frequency was 10Hz. As a result, following conclusions were obtained. Peaks of diffraction intensities of 1% and 15% alkali treated jute fiber appeared at 22.8° and 22°, respectively. This phenomenon indicated that cellulose in constitution materials of 15% alkali treated jute fiber changed cellulose I to cellulose II. Fatigue strengths of non, 1% and 15% alkali treated jute fiber decreased with an increase of number of cycle. Fatigue strengths at 10 6 cycles of non, 1% and 15% alkali treated jute fibers were 280MPa, 320MPa and 181MPa, respectively. The number of crack in surface of jute fiber at 10 3 cycles increased with an increase of alkali concentration of treatment. Therefore, fatigue property and damage of jute fiber was affected by alkali concentration of treatment.

In this study, the effects of alkaline and silane surface treatments on the tensile property of jute fiber were investigated. Surface treatments were conducted in distilled water with 1 to 5% concentrations at room temperature (RT) for two hours. A quasi-static tensile test was conducted. Environmental temperatures were RT, 50°C and 100°C. As a result, the tensile strengths of 1% alkaline treated jute fiber were higher than those of virgin materials under all environmental temperatures. The Young's modulus of alkaline treated jute fiber under 50°C was higher than that of virgin material. The Young's modulus of alkaline treated jute fiber under 50°C was higher than that of virgin material. But, Young's modulus of alkaline treated jute fiber under 100°C almost did not change. It is thought that the tensile property of jute fiber was affected by the rate of cellulose in jute fiber after alkaline treatment. On the other hand, the tensile strength of silane treated jute fiber under RT was higher than that of virgin materials. Tensile strength of silane treated jute fiber under 50°C and 100°C almost did not change. Young's modulus of silane treated jute fiber under RT was higher than that of virgin material except for 5% concentration. And, Young's modulus of silane treated jute fiber under 50°C was higher than that of virgin materials. But, Young's modulus of silane treated jute fiber under 100°C almost did not change. Therefore, the tensile property of jute fiber at less than 50°C was affected by silane treatment because of the coupling silanol group with a surface of jute fibers.
