In the Life Cycle Management context of complex systems there are a few “families” of products which, due to the aleatory behavior of the development and production processes, present difficulties in the management of the remaining usable life and spare parts approach. One of such “family” is represented by composite materials and products. This article proposes a methodology to improve their support through the mapping of the zonal/functional characteristics of each item on a LSA Database (ASD S3000L will be used as the example).
