Abstract
This paper describes the flexural properties of biodegradable composites made using natural fiber and biodegradable plastics. Biodegradable composites were fabricated from bamboo fiber bundles and PLA (polylactic acid) resin. In this research, effect of molding temperature and fiber content on flexural properties of bamboo fiber reinforced composites was investigated. The flexural strength of this composite increased with increasing fiber content up to 70%. The flexural strength of composites decreased at molding temperature of 180°C. Biodegradable composites possessed extremely high flexural strength of 273 MPa, in the case of molding temperature of 160°C and fiber content of 70%.
Highlights
Consciousness to recycling and zero emission is increasing
The present study investigated whether bamboo can be effectively used to replace plastic and FRP materials
The flexural strength of this composite increased with increasing fiber content up to 70%
Summary
FRP (fiber reinforced plastics), including glass and carbon fiber reinforced plastics, have good characterizes, such as high strength, low density and corrosion resistance. These FRPs are extensively used in a wide range of fields, including a exterior of a motorboat, automobile parts and sport goods, etc. They are made from fossil fuels and they are non-biodegradable From these perspectives, the usage and disposal of conventional FRP clearly contribute to the global concerns of recycling and zero-emissions and emphasis need to be placed on the involving FRP once they have been disposed
