Effects of Plasma Treatment on Bonding CFRP

By removing surface contaminants, plasma treatment can improve the bondability of CFRP.

August 2, 2022

Thanks to their strength, corrosion resistance and formability, carbon fiber-reinforced polymers (CFRP) are increasingly being used for automotive and aerospace structures. Adhesives are ideal for assembling CFRP.

Manufacturing large, monolithic composite parts, such as a car body or an aircraft fuselage, requires a large and complex mold. As a result, the process can be quite costly. Alternatively, such complex parts can be manufactured less expensively by assembling a series of smaller parts using various joining techniques.

Automating Carbon-Fiber Composite Fuselage Assembly

Traditionally, aircraft manufacturers have been reluctant to adopt robots and other types of automation. One of the main challenges is that large plane parts come with relatively high geometry deviations, so robots need sensor guidance.

New Materials, New Fasteners

As automakers replace steel with lightweight materials, new fasteners will replace conventional screws.

Steel has been, is now, and will continue to be the predominant material for vehicle structures and body parts, such as doors, hoods, liftgates and fenders. But, other materials, such as aluminum, magnesium, plastics and composites, are becoming increasingly important.

New Developments in Self-Pierce Riveting

New technology incorporates the advantages of self-pierce riveting while overcoming its limitations.
