|Abstract:||The environmental corrosion of carbon-fiber/epoxy and E-glass/epoxy composite laminated aluminum alloys [e.g., Al 1100-H14, Al 5456-H116 (non-sensitized), Al 5456-H116 (sensitized), and Al 7075-T6] was studied to characterize the interfacial corrosion between the composite and the aluminum substrate. Samples were exposed at 5 locations around the islands of Hawai’i that represented alpine, marine, severe marine, rainforest, and volcano environments over 1-month, 6-month, and 12-month time periods. After exposure, the samples were then adhesion strength tested by conducting pull test to remove the composite laminate from the aluminum substrate to determine the loss (if any) of the composite laminate adhesion to their respective aluminum substrates. The delaminated samples were then analyzed with a scanning electron microscope and energy dispersive X-ray analysis to determine the distribution of corrosion products and ionic species at the aluminum substrate - composite laminate interfaces. The decay in adhesion strength was correlated to the amount of corrosion at the interface that was dependent on the type of composite and type of aluminum alloy.|
