Abstract

JUNIOR, Mario Guimarães et al. Physical and chemical characterization of fiber and pulp of Bambusa vulgaris Schrad for use in polymeric composites. Rev. LatinAm. Metal. Mater. [online]. 2013, vol.33, n.1, pp.33-42. ISSN 0255-6952.

Nowadays the interest in polymeric composites reinforced with vegetal natural fibers in substitution for manufactured fibers is increasing. This is due to the fact that vegetal fibers are less abrasive, biodegradable, present low density and excellent mechanical and thermal properties. Several vegetal fibers have been used for various types of composites among which the bamboo differs from these fibers in being widely used for cellulose and paper industrial production. This paper presents the results of recent researches about fiber and pulps of bamboo, which were submitted to several types of tests, aiming at a better understanding of their properties. The main objective of this study was to physical-chemical characterize fiber and bamboo pulps, disseminating their properties and maximizing their use in polymeric applications. Most of the samples were analyzed and characterized using the methods recommended by the American Society for Testing and Materials, ASTM and the Technical Association of the Pulp and Paper Industry, TAPPI. The results show that the refined pulp was more suitable to be used as a reinforcing agent in polimeric composites instead of the unrefined pulp and natural fiber.

Keywords : polymeric composites; vegetal fibers; bamboo pulps.
