Randomized trial evaluates surface treatments' impact on interfacial behaviour in aluminium-carbon fibre laminates, suggesting improved structural performance.
Key Points
This study aims to evaluate how different surface treatments affect the interfacial fracture behaviour of aluminium-carbon fibre metal laminates.
Compared various aluminium surface treatments including mechanical, chemical, electrochemical, sol-gel, and primer coatings.
Conducted shear strength measurements and load-displacement response analysis.
Used scanning electron microscopy for cohesive failure assessment and fracture analysis.
P2 etching and chromic acid anodizing increase adhesion at the metal-composite interface by approximately 62% and 67%, respectively, compared to sandblasting.
Sol-gel coatings enhance interfacial adhesion and improve stress transfer, shifting crack propagation into the composite volume.
