摘要：

The paper presents the evaluation of stiffness and flexural rigidity in case of a spherical cap sandwich structure with thin nonwoven polyester mat as core. The structure is formed of twelve curved shells and presents dissimilar skins from which one is a glass fabric reinforced polyester. Three-point bend tests have been carried out to determine the most important features of this structure, as well as a finite element analysis. Stresses and strains have been measured using strain gauges applied on a curved shell subjected to bending. The experimental researches accomplished on specimens manufactured from the same material as the structure present a twelve times increase of the flexural rigidity against the upper skin one.
