ABSTRACT
We developed a new method for the design of carbon-fiber reinforced plastic (CFRP)-laminated structures, which combined the asymptotic homogenization method and ply optimization. The equivalent mechanical properties of a single-layer CFRP were calculated using the asymptotic homogenization method. The ply optimization of the laminated structures was divided into three parts: an initial free-size optimization to identify the optimal ply shapes and locations of patches per ply orientation; an optimization of the final size to identify the optimal thicknesses of each ply; and an optimization of the final ply stacking sequence to obtain the optimal stacking sequence. Using the example of the floor of a body-in-white model, our method provided a reasonable optimization result with reduced mass by 60 %. The proposed method provides an efficient way to investigate laminated structures and has potential for lightweight design and analysis of automobile components.
Key Words: Laminated structures, Asymptotic homogenization method, Ply optimization, Vehicle body
