Some Aspects Concerning the Mechanical Characterization versus Manufacturing Technology of Sandwich Composite Materials

Abstract:

The paper presents aspects observed during classic three-point test bending of various sandwich materials. These aspects outline the need to spare special attention to such test, in connection with the particular material and service life conditions it will endorse. Such special care is needed in conditions of scarcity of dedicated standards and some evasive formulations in the existing ones.
