Tensile Properties of Bamboo Fiber Reinforced Biodegradable Plastics

Abstract

This paper describes tensile properties of bamboo fiber reinforced biodegradable plastics. The unidirectional biodegradable composites were made from bamboo fiber bundles and a starch-based biodegradable resin. The tensile strengths of the composites increased with increasing fiber content up to 70%. The composites possessed extremely high tensile strengths of 265 MPa. The fabrication with emulsion-type biodegradable resin contributed to reduction in voids and fiber contacts in the composites. Moreover, heat resistance of bamboo fibers and bamboo fiber reinforced plastics was investigated. As results, tensile strength of both bamboo fiber and bamboo fiber reinforced plastics decreased at 160℃.

Heat Influence on Physical and Mechanical Properties of Dendrocalamus Giganteus Bamboo

“…Based on this report the degradation of the bamboo fiber starts from 140°C butinthisrangehasnotbeenobservedanychangesin young'smodulusalmost constant and independent of the heat treatment condition. In the other research about tensile properties of bamboo fiber reinforced biodegradable plastics by the same author Ochi (2012) [69] shows that the tensile strength of both bamboo fiber and bamboo fiber reinforced plastics decreased at 160°C.…”

The use of bamboo fibres as reinforcements in composites

“…Another method used to separate bamboo fi bres is the steam explosion method. In steam explosion, the water contained in bamboo is heated under high temperature and pressure and the pressure is then rapidly released to the atmosphere, so that the water evaporates, shattering the parenchyma inside the bamboo (Ochi, 2012 ). This method is more environmentally friendly compared to the chemical process; however, it is rarely used because it is expensive.…”

The Elastic Properties of Unidirectional Bamboo Fibre Reinforced Epoxy Composites

“…Experimentally, tensile test was conducted by Ogihara et al [23] on bamboo fibre composite and it was found that tensile strength increases with increasing weight fibre fraction for wt% of less than 30%. Furthermore, Ochi [24] managed to increase volume fraction of bamboo fibres in a starch-based emulsion-type biodegradable resin up to 70% where after conducting tensile test, the composites gave high tensile strength of 265 MPa and tensile modulus of 12.4 GPa. Sapuan et al [25,26] conducted several experimental procedures to determine mechanical properties of several chemically treated and non-treated natural fibre composites including sugar palm and kenaf.…”
