Abstract: This preliminary research was directed toward understanding the fundamental science behind polymer matrix-adhesive interactions in adhesively bonded composite aircraft materials throughout the product’s lifecycle. Nanoindentation techniques were used to characterize various regions of adhesively bonded carbon fiber/epoxy composite samples including the matrix resin, adhesive, and bondline mixing zones (interface/interphase). For this study, nanomechanical properties of a cobonded bonding system were evaluated after short durations at high temperature. Nanomechanical testing was used to understand the differences between initial interface and/or interphase development and the adhesive interface/interphase after high temperature exposure conditions. Previous studies using standard mechanical property characterization methods have not been able to isolate the adhesive/adherend interphase, due to the micron-sized scale of these regions. Nanomechanical test methods can be used to measure the adhesive/adherend interphase specific properties. Future work is to further understand how these nanomechanical properties can be related to bond quality and performance.
