Strain and Fracture of Glass-Fiber Laminate Containing Metal Layers

Аннотация

This paper describes an experimental study on strain and fracture of plane samples made of glass-fiber laminate and fabric-based laminate with surface and inner aluminum layers. It is shown that the presence of these layers reduces the strength of glass-fiber laminate under static and low-cycle loading. This can be explained by the fact that the stretching of a hybrid composite along the layers is accompanied by the formation of localized tensile regions of glass-fiber laminate across the layers. As a result, both the hybrid composite and its glass-fiber laminate component are stratified.
