Design and test of continuous fabrication process for high-strength nanocellulose based long-fiber

초록

A continuous fabrication process for high-strength nanocellulose based long-fiber (NLF) has been researched as a key process to fabricate natural fiber-reinforced polymer composites with high specific modulus and strength. The process was custom-designed by utilizing the wet spinning and stretching methods with dry process. First, nanocellulose was isolated from wood pulp by using a combination of chemical and physical methods. Apparatus for the process was self-produced and the process parameters such as the speed, position, number of wheels were experimentally investigated. Among the various designs, two specific setups were chosen and the speed of the wheels was optimized. The success of the process was determined by the sustainability of the setups for more than 30 min. The results were evaluated by using the tensile test and scanning electron microscope.
