Challenge: Forming processes for carbon-fibre stringers with complex contours
Stringers are widely used (4 to 6 km) in aeroplane structures to provide stiffness to the panels. In wings and certain areas, stringers must follow complex contours.
Current technologies have low productivity and are unable to form contoured stringers without wrinkles.
There is a need for a high productivity, automated system able to make different types of straight and contoured stringers.
A+ GLIDE FORMING
The revolution in stringer manufacturing
Applus+ has developed a new stringer manufacturing process to provide a versatile, high-productivity and low-investment forming solution that overcomes the major drawbacks of existing forming technologies.
Forming Technologies Comparison
A+ Glide Forming Benefits
One single machine for different stringers: Ω, T, U
Only a new male tool is needed to manufacture an additional stringer
OPEX: highly automated, low labor cost
CAPEX: only one machine, very simple tools
Local heating: no heating tools, energy saving compared to current technologies
Less scrap material
Contoured formed L and Ω
