Abstract
This study aims to determine the effect of liquid smoke treatment on the tensile strength of the single fiber and Coconut fiber (CF) Reinforced Composite. The research method is Immersion the fiber with liquid smoke and heating. First treatment, CF was immersed in liquid smoke for 1, 2, and 3 hours, then dried for 1 hour at a temperature of 40 degrees Celsius. Next, the single fiber tensile test was carried out with the Universal Impact Test Machine and composite impact strength. The results showed that the tensile strength of single fiber TP, P1J, P2J, and P3J of 51.357 MPa, 79.655 MPa, 48.187 MPa, and 58.117 MPa. While the CF composite impact test TP, P1J, P2J, and P3J of 0.514 KJ/m2, 1.385 KJ/m2, 1,085 KJ/m2, and 2,128 KJ/m2. The liquid smoke immersion can increase the tensile strength of single fibers, where 1-hour immersion has the greatest value. In contrast, the impact strength of the CF composites increased at 3 hours, the largest immersion value. The results showed that the fiber soaked in liquid smoke could be an alternative to improve the mechanical properties of CF.
Highlights
The development of research that utilizes renewable and biodegradable materials to replace metal materials is very rapid [1][2][3][4]
Effect of treatment of liquid smoke on the tensile strength of the single fiber in which the test results showed the tensile strength TP to 51.357 MPa, P1J increased tensile strength is significant for 79.655 MPa
It can be concluded that the lowest tensile strength of a single fiber is liquid smoke immersion for 2 hours of 48.187 MPa, and the highest tensile strength of a single fiber is the immersion of liquid smoke for 1 hour of 79.655 MPa
Summary
The development of research that utilizes renewable and biodegradable materials to replace metal materials is very rapid [1][2][3][4]. Researchers are currently focusing on non-metallic materials from fibrous plants because the fiber can be used as a composite reinforcement and is easy to obtain, inexpensive, and has mechanical properties [5][6], such as sago sheath fiber [6], bamboo fiber [7]., pineapple fiber [8], and palm fiber [9]. North Maluku, as one of the eastern provinces of Indonesia, is one area that has the potential to research natural fibers into composite reinforcement materials, where there are several studies on natural fibers that have been carried out in eastern Indonesia, including sago fiber, king pineapple fiber, fiber fibers, and others [10][9]. The coconut belt consists of an outermost layer (exocarpium) and an inner
