Lightweight aircrafts, based on composite materials, represent the primary goal of aerospace industry in the close future, allowing considerable savings in aircraft operation costs. Carbon Fiber Reinforced Plastics (CFRP) panels are the basic components for lightweight aircrafts. Their assembly is primarily based on adhesive technologies but, currently, no NDT technique has been validated for ensuring the quality of the bonds while low quality bonding, often caused by surface contamination, would lead to weak bonding with potential airframe failures. Operative needs such as portability, rapid response, versatility make e-noses to represent an interesting solution to develop an ad-hoc tool for surface contamination detection in this scenario. In this work we present the results of a sensor selection procedure for such an e-nose based tool.
