RÉSUMÉ

For the first time, fatigue and residual strength tests were performed on the wing box, which was manufactured using a polymer composite material according to a new infusion technology. The effect of technological (porosity, delamination, etc.) and operational (impact) defects on the durability and residual strength of the structure is evaluated.
