Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2020 / V.32,no.4,Dec Title Comparative Study on Mechanical Properties of Sonicated Bamboo and Kenaf Fiber Composite Authors Su Kyoung Lee1,2*, Eun Young Park1,3, Tae Sung Park2 and Seung Kook An1 Institution/Affiliations 1Pusan National University, 2,3KIFLT Pages/Total page pp.274 ~ 280 / 7 Language Korean Abstract This study compared the mechanical properties of bamboo fiber composites and kenaf fiber composites through physical treatment (ultrasonic treatment). Kenaf, a composite of PP reinforced with bamboo fiber, was made using injection molding technology. PP was used as a binder and the ultrasonic treatment time of bamboo and kenaf was increased by 30 minutes to compare and study various mechanical properties of bamboo and kenaf composites through physical treatment. Interfacial properties such as internal cracks and internal structure of the wave cross section were confirmed using a scanning electron microscope (SEM). As a result of the ultrasonic treatment, most of the characteristics were fragile as the ultrasonic treatment time was increased, and it was confirmed that the natural characteristics of the twisted fibers had a great influence on the characteristics of the composite material.
