Abstract
With the development of cheaper composite materials and more efficient manufacturing processes, there has been a steady growth in the applications as well as the interest of small and medium scale enterprises to manufacture composite parts. Current methods for cost estimation of composites require many inputs and CAD models. The methodology developed in this thesis will enable manufacturers and designers to obtain a preliminary cost estimate for composite parts based on minimum information during the early design stages. The total cost estimate calculated in this thesis follows the break-down approach where the total cost is broken down into its primary and secondary cost components. The break-down model follows a hierarchical structure of calculating the usage of materials and time, which are at a lower level, based on the user inputs and then using these lower level costs to calculate the upper level cost estimates. The results show the implementation of the methodology in an Excel tool which can be used to estimate costs of different parts using different materials and processes. The comparison between the actual and estimates cost for a test composite part shows an error of 8.58% with a 95% probability that the actual cost would be in a range of $150 above or below the estimate.
