Sandwich Shear Test Revisited

A technique and new equipment for shear tests of sandwich materials are described. The shear strength and rigidity of two sandwich composites were studied experimentally. The results of shear tests on laminated materials with a honeycomb filler are analyzed. It is found how the shear strength and rigidity depend on the type of the material and the dimensions of a honeycomb as well as on the direction of the shear load relative to the planes of the adhesive joint between the honeycomb walls. The investigations preformed may be used to work out a shear test standard for fillers of sandwich materials
