Variation Analysis of Carbon Fibre Reinforced Polymers Light Weight Aero Engine Parts

In this paper the focus is on variation analysis for composite CFRP (carbon fibre reinforced polymers) parts. A detailed study of possible sources of variation in manufacturing of CFRP parts is presented. Based on the variables identified a simulation chain on how to manage and simulate this variation is described. This paper also presents a logical approach to how a digital twin for a fully automated production line of compression molded CFRP parts can be built, and to investigate and quantify how much each individual variable contributes to the final variation in the component.
