Rampf Composite Solutions provides complete solutions for composite parts in the aerospace sector for better automation in the aerospace industry, thereby increasing the cost-effectiveness of composite production. For this, the company uses tailor-made fiber placement technology and a liquid resin system.
Rampf's manufacturing and process solutions include material qualification, comprehensive quality assurance and automation for structural and interior applications. The benefits of this approach are especially evident in the manufacture of components with high geometrical complexity structures (dimples, bends, dents, etc.) and must meet difficult functional specifications (electromagnetic shielding, electrostatic discharge, impact protection, flame retardant).
Tailored fiber placement includes defined stiffness and strength, maximized by selectively placing and arranging carbon and glass fiber filaments where strength or weight optimization is required. This optimizes the structural performance of lightweight components – while minimizing weight, carbon fiber consumption and cost.
Special liquid resin systems (with or without FST properties) penetrate quickly and efficiently into TFP preforms: in addition to good wetting properties, these systems are also suitable for low temperature processing, e.g. for resin infusion at 40°C . In addition, key process steps – such as mixing, degassing and metering – are largely automated.
The company cited the replacement of stainless steel components used in commercial aircraft with lightweight components made almost entirely of carbon fiber composites as an example of the potential of this complete solution. The weight of the part was reduced to about one-fifth of the original part without adding cost.
According to Rampf, users have even realized additional operating cost savings through this significant weight reduction measure. In addition, only 5 precast panel laying tools are required to be produced. If traditional composite design methods and materials were used, the number of precast panel laying tools would be 75. Almost all airliners now use this component.
"With our solutions, the process of reducing aircraft weight and improving fuel efficiency is more automated and cost-effective. Our highly skilled team of experts handles all tasks required to design complex composite aircraft components – from sketch to validation" . Relevant personnel said so.
