Impact Analysis of Aluminum-Fiber Composite Lamina

抄録

Hybrid materials of fiber composite and aluminum alloys have a great potential in reducing the weight of transportation vehicles. It has been become an alternative solution to steel panels because they can provide high strength and improving energy absorbing capability under impact and collision loading. Developing a new composite material based on experiment by changing mechanical properties is quite expensive and takes long time. Therefore, numerical simulation with the aide of FEM is often performed, since its results have been proved to be close to the experimental ones. There are many different ways in which the fiber can be combined into the resin. In this paper, the effect of lining arrangements of composite materials and the orientations of the layers on the strength was simulated using FEM in which the adhesive bond between fiber composite/metal is assumed as a tie constraint. Several plate panels with different lining arrangements and subjected to impact loads were investigated. The results of analyses are presented and their trends are discussed.
