摘要：

The effect of cyclic corrosion on the static strength performance and reversibility performance of multi-material single lap joints is investigated. Aluminum substrates are adhesively bonded to Carbon-Fiber-Reinforced thermoplastic composite substrates using a commercially available two-part epoxy. The adhesive is modified with Thermally Expandable Particles at various concentrations by weight, with the purpose of allowing for joint separation using a charged RF coil to evaluate reversibility performance. The quasi-static performance of baseline joints is assessed, and the results from the various particle concentrations are compared. The cyclic corrosion testing of the Single Lap Joints is performed in accordance with a GMW 14872 3 stage laboratory standard for different lengths of duration up to 57 cycles. Quasi-static lap shear tests are performed at various stages of corrosion cycling and compared. Results and conclusions are provided.
