The increased demand for high strength, light weight materials that function successfully in high temperature environments has caused the effective development of laminated composites to become critical. This paper focuses on the continuing research effort to develop a computational capability for the optimization of laminated, fiber reinforced composite structures. This work has resulted in several working computer packages, utilizing such optimization methods as feasible directions, optimality criteria, and simulated annealing. Creation of such computer packages that provide user flexibility as well as ease of operation was a priority. The basic concept of optimization was also studied to better understand how an optimum design is defined, and what criteria should be used to achieve the optimum.
