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

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 car hood is one of the automotive parts which damage from the accident. Consequently, the researchers have created a prototype material to develop into the car hood, which made from the husk and water hyacinth. The random mixture of water hyacinth and husk was attempted to more than 3 ingredients. By forming, a flat plate with thickness between 1 to 3 millimeters was used as prototype of the car hood material in this research. Thus, the mechanical properties such as compressing and bending test were attempted to by the universal testing machine. The results showed that using resin as a binder material (Reinforced resin by water hyacinth and husk) will have the less ability of energy absorption. While, using polymers as a binder (Polymer resin by water hyacinth and husk) will have the better ability of energy absorption. The properly mixture between water hyacinth and husk referred to the energy absorbing properties is 50:50 because the least linear stiffness is 1.087 N/mm. Besides, the ability of energy absorption is 1,612,444 J/m3, which is property of this ingredient can reduce the severity of the impact in the event of pedestrians collision in the best.
