The art of finishing a million-pound sandwich...

Most people don’t realise that aerospace composite components are essentially high-tech sandwiches - carbon fibre, resin, perhaps some honeycomb, all layered for strength and lightness.

Now imagine trying to finish that without damaging it.

You can’t simply sand or polish - this is precision surface engineering for parts that fly at very high speeds.

That’s where wet blasting comes in.

It’s like calibrating a surface rather than abrading it:
• Water cushions the abrasive
• Energy is carefully controlled

The result? A uniform, bond-ready surface that’s free from resin gloss and perfectly keyed - without micro-cracks, fibre damage, or heat stress.

Every time a composite fairing or nacelle panel is finished, we’re reminded: Innovation isn’t always about adding layers - sometimes it’s about how precisely you prepare them.
