Composite materials are now central to defence and aerospace programmes, particularly for composite drone blades, aircraft propeller blades and helicopter rotor blades where strength, weight and reliability are critical.
But performance isn't simply about the material itself. It's also about how the surface is prepared before bonding, painting or coating.
When composite blades leave the autoclave, they are often left with a waxy, hydrophobic residue. This causes paints, lacquers and adhesives to bead on the surface, limiting coverage and reducing bond strength.
