Plasma Treatment for Aerospace – Stronger Bonds, Lighter Structures

Plasma technology has become a pivotal solution in aerospace manufacturing, offering fast, controllable, non-destructive surface treatment across complex geometries. For carbon fiber reinforced polymers (CFRP), whose high strength-to-weight ratio delivers major benefits in fuel efficiency and payload capacity, plasma provides a highly controllable activation method that overcomes low surface energy.

Plasma treatment demonstrates a 40% improvement in lap shear strength on carbon fiber composites compared to untreated surfaces, outperforming solvent wiping, hand sanding, and even laser ablation. The technology is used throughout the aerospace value chain, including engine and structural components, fuselage and wing parts, and interior and functional components.

Plasma processes require no solvents or VOCs, generate no hazardous waste, and integrate seamlessly into existing production environments. Plasma pens have already been adopted in the aerospace sector for improving adhesion in various applications.

Additional benefits include enhanced corrosion resistance through protective coatings and improved wettability for advanced composite bonding. By leveraging plasma technology into inline processes, aerospace manufacturers achieve stronger, more durable joints while reducing weight and improving fuel efficiency.
