The effect of NaOH concentration variation in the process of paper making from bamboo fiber

Abstract

Bamboo cropping period is quite short compared to wood, but fiber and bamboo pulp have not been optimally used as a substitute for wood in composite industry, such as fiber board. It is worth to be investigated because of the availability of wood is declining. Therefore, this research aimed at revealing the use of fiber and bamboo pulp (G. apus) for fiberboard. The study was conducted using bamboo fibers from bamboo strips cooked with soda process and bamboo pulp from chips of bamboo cooked with soda process and Kraft process. Composite of bamboo fiber is made with a variety of fiber weight fraction to the epoxy resin matrix. Furthermore composite of bamboo pulp is made under optimal condition for making fiber composite. Based on the test results, it is known that the quality of the bamboo fiber composite from bamboo strips cooked with soda process is better than the composite of bamboo pulp. Besides, the produced bamboo fiber composites can be categorized as the high-density fiberboard meanwhile for the aspect of water content, water absorption, length and thickness changes, flexural strength and modulus of elasticity are in accordance with applicable standard for fiberboard (SNI 01-4449 - 2006).
