INVESTIGATION OF HYDROTHERMAL AGING MECHANICAL PROPERTIESOF GLASS FIBER-ALUMINUM LAMINATE

Abstract

Abstract: The mechanism of hydrothermal aging of glass fiber-aluminum laminate was studied by analyzing their mechanical properties, IR spectra, morphology and elemental changes of aluminum alloy, as well as the hydrothermal aging include different aging cycles at 70 ℃ and 85%. The results show that under the condition of accelerating the hydrothermal aging, the inner matrix of the composite material will be hygroscopic and plasticized, and destroy the interface of resin-fiber and resin-aluminum, which will affect the internal stress transmission and the mechanical properties related to the interface and bridge stress. The aluminum alloys are oxidized with hydrothermal aging time, so that the plasticity of aluminum decreased, and the mechanical properties of the laminate are affected.

Key words: hydrothermal aging, glass fiber-aluminum laminate, interface, bridge stress
