To clarify the advantages of mathematical optimization of multi-targeted, in part, the author conducted done optimizing design maximum of composite beams with variable goals for rf design has to consider binding in the production process. The greatest value of the rf can be achieved in the production process are determined based on the arrangement of the fibers in a layer (Pelletier & Vel, 2006). In that, if the arrangement of fibers form a square or hexagonal shaped fiber arrangement. In this section, then the rf design variables have the maximum value selected is 90.69%, thickness of each ply t = 60 mm and are made for two different fiber orientation angle case: [00/900/450/450] S and [450/00/900/450] S.
