This paper presents a collection of tools for conceptual structure design, called MOPED. The underlying model is the free material optimization problem. This problem gives the best physically attainable material and can be considered the "ultimate" generalization of the structurallshape optimization problem. The method is supported by powerful optimization and numerical techniques, which allow us to work with bodies of complex initial design and with very fine finite-element meshes, giving thus quite accurate solutions even for bodies with complex geometry. The computed results are realized by composite materials. We consider a particular class of fibre-reinforced composite materials manufactured by the so-called tape-laying technology. In the post-processing phase, we plot curves which indicate how to lay these tapes; they also show the proposed thickness of the tapes. Examples demonstrate that MOPED is an ideal tool for conceptual design of engineering structures
