Bonding performance of a hybrid epoxy adhesive on oil-covered substrates

Wednesday, 28 October 2015

Researchers prepared a hybrid multiscale epoxy adhesive reinforced with a combination of short carbon fibers and rubber nanoparticles for bonding oil-covered aluminum substrates.

The shear performance of the bonded joints was investigated as a function of the oil layer thickness. Scanning electron microscopy and energy-dispersive X-ray analysis studies were carried out to evaluate the oil-diffusion behavior near the substrate-adhesive interface.

Shear strength decreased

The results show that the shear strength decreased, whereas the distribution range of the testing results increased as the oil layer thickness increased. When the oil layer was thinner than 10μm, the oil-accommodating adhesive could be used directly without degreasing, whereas over 96% of the bonding strength could be retained with almost no change in the failure probability. The analysis of Weibull distribution indicated that the shear strength and Weibull modulus were 18.89MPa and 13.503, respectively. By analysing the relationship between the shear strength results and the failure model of the fracture surface, the researchers found a correlation.

The study is published in: Journal of Applied Polymer Science, Volume 133, Issue 3, January 15, 2016
