Central Material Concept: Towards Aircraft Wing Structure Insensitive to Fatigue

Over the last two decades, some groundbreaking research concerning materials has been published. Major improvement of material is still, nevertheless, robust manifested in the recent development termed CentrAl. The work reported in this research serves two purposes. First, in response to concerns regarding fatigue problems in aircraft structures, it is shown how to realize the benefits of this concept. The second part of the work aims to contribute to the existing dearth body of knowledge on CentrAl concept to bridge the gap between theory and operational practice. Grounded in state-of-the-art literature, current insight for the deficient research in CentrAl are identified and presented n the form of required experimental process. The ultimate research goal aims to analyze and summaries the present state and future tendency in the different approaches of metal and fibre composite layer combination. The achieved results with the support of CentrAl are discussed in detail and compared whenever possible with previously published results on Glare to lay out the applicability of CentrAl concept to aircraft wing structures insensitive to fatigue.
