CHAPTER 1 – INTRODUCTION 1.1 INTRODUCTION From year to year, the number of vehicles on the road based on the development of automobile and transportation industry has increased year by year. To more dependence on transportations frameworks. The interest for vehicles has been expanding for a current society is all the more better. Subsequently, the vehicle crash accident has become a major problem for worldwide health. This is caused by road vehicles such as vans, trucks, cars, buses and heavy vehicles. A motor vehicle can be involved in the variety of crash events, each causing human injury of the different method. Table 1-1 provides a more detailed analysis of the nature of crashes in Malaysia in 2010 grouped by the severity of each crash type. Table 1-1 Crashes by nature of crash and severity in Malaysia in 2010 (http://www.mot.gov.my) [Accessed May 2014] In addition, Figure 1-1 shows how the nature of crashes changes in relation to the severity of crash. From this information, the road crashes obviously constitute a great economic for worldwide health problem. The energy absorption capacity of protective and vehicles structures has become more important for safety requirements. …show more content…

It has higher specific stiffness, higher specific strength, and better thermal insulation properties compared with other engineering materials. The characteristics of foam are usually described by its relative density, (are the densities of foam and solid material of the cell wall, respectively), and stating whether it is open or closed cell, as reported by Gibson and Ashby [45]. For the open-cell foam, the cell walls are broken and air fills all the spaces in the material (Figure 2-3a). Thus, this type of foam is soft and weak. While in the closed-cell foam (Figure 2-3b), most of the cell walls are not broken and they are resembled together in a compact configuration in order to make them strong enough to undergo large
