Mechanical characteristics evaluation of wood plastic composites used thinning wood

Abstract

In this paper, wood flours having a microfibrillated cellulose network on the surface were proposed for wood plastic composites to improve mechanical properties. Wood flours were fabricated through wet milling process. The average of particle size was arranged to approximately 26μm. Then the surface of wood flours was melted by ionic liquid and the microfibrillated cellulose network was generated. The thinning woods such as chamaecyparis cypress and cedar were utilized for raw material. 1-Butyl-3-Methylimidazolium chloride was employed for ionic liquid. The nature of ionic liquid treated wood flours were observed by SEM. The test specimen of wood plastic composites was fabricated by injection molding. Polypropylene was used for matrix. The influence of ionic liquid treatment on mechanical properties was discussed.
