Effects of Mechanical Surface Treatment on Bonding between Aluminum and Carbon/Epoxy Composites

Carbon fiber reinforced polymer composites, especially carbon/epoxy, have been attracting interest from offshore oil and gas industry as alternatives to metals for deepwater risers due to their very high performance besides being light weight. Composite risers, however, require an inner liner of met...

In this study, two mechanical surface treatment methods, grit blasting and grooving, are used to modify aluminum liner surface.
