Creation of a ‘wet-out’ surface for composite bonding
The image above is an excellent demonstration of the effect wet-blasting, or vapor blasting to give it its other name, has on composite surfaces.
Note how the water evenly sticks to the clean wet-blasted area on the right and is repelled from the un-finished surface on the left. A similar effect occurs with adhesives, lacquers, and paints.
It also explains why wet-blasting composite surfaces is important for maximum composite bonding strength.
Visit our dedicated composites industry page to see a video of a ‘wet-out’ surface being created by wet-blasting – watch to the end to see the strip of composite in the image.
