A possibility of hood produced by rice hull and water hyacinth for pedestrian protectionsPichest

Abstract

Recently, the Thai industry has continually grown up and also plays a role to economic growth in the country which affects the many of automotive components to be in the market. While the degeneration and waste of automotive components had increased as well. Therefore, a crash box is one of the automotive parts which damage from the accident. Consequently, the researchers have created a prototype material to develop into the crash box to reduce the environment problem from automotive parts. The random mixture of water hyacinth and husk was attempted to up to 5 ingredients. By forming, a solid cylinder and 200 mm of long was used as prototype of the crash box in this research. Thus, the energy absorption using compressing test was attempted to by the universal testing machine. The results showed that using polymers as a binder with 50% of water hyacinth and 50% of husk was the better ability of energy absorption. Regarding this ingredient, 1,612,444 J/m3 of the energy absorption was referred to indicate that is the best ability of energy absorption. It is probably reduce the severity of the impact in the event of pedestrian collision.
