EFFECT OF SALT SPRAYON MECHANICAL PROPERTIES OF GLASS FIBER-ALUMINUM LAMINATE

Abstract

Abstract: The mechanism of salt spray aging of glass fiber-aluminum laminate was investigated by analyzing their mechanical properties and IR spectra. Under the condition of accelerating the salt spray aging, the inner matrix of the composite material was degraded, and the resin-fiber interface and the surface of the aluminum alloy corrosion damage occurred. With the extension of aging time, the tensile, compression and in-plane shear strength of 0 ° and 90 ° laminates showed a significant decreasing trend,while the laminate interface of 90°specimen suffered more serious damage. The degree of cross-linking of the thermosetting resin matrix inside the composite layer was reduced. Also, the resin-fiber and resin-aluminum interfaces were destroyed, consequently affecting the material internal stress transmission and the mechanical properties.

Key words: salt spray aging, glass fiber-aluminum laminate, interface
