GFRP leaf springs

IFC Composite has positioned itself as the technological global market leader for glass-fiber reinforced plastic (GFRP) leaf springs. The company has been mass-producing GFRP leaf springs since as early as in 2005. The product range for GFRP leaf springs has been expanded since then, for instance, with the 'heavy goods vehicles' segment. GFRP leaf springs offer significantly reduced weight.

The GFRP leaf springs for 40-tonne trucks were unveiled as a world first at the International Motor Show in Frankfurt in 2011. The very high demands in the truck sector were easily met by the product of the future. IFC Composite considers GFRP leaf springs to be a promising growth market for the future.

The particular charm of the highly economical and innovative leaf springs lies in their positive environmental impact during manufacturing and use. The structural component from Haldensleben is characterized by its sustainable environmental compatibility, both in production and in operation. The saved weight reduces the vehicles' fuel consumption. This, in turn, significantly reduces carbon dioxide emissions. The fine response characteristics of the high-performance springs minimizes rolling noise pollution for the environment.

Compared with a leaf spring made from steel, the product offers significant advantages, not only in terms of weight and environmental compatibility, but also in all other relevant areas. This is because GFRP leaf springs are also more economical, more convenient and longer-lasting. IFC Composite has amassed a great deal of experience in development and manufacturing. What's more, the high-tech company also has a complete in-house process chain.

More than 1.3 million of the dynamic and highly resilient GFRP leaf springs, which have an error rate of 0 ppm, have already been supplied for light duty trucks. IFC Composite is convinced of its success and expects the fiber composite product to undergo a comprehensive industrial break-through for heavy commercial vehicles as well.


The prepreg technique is the most high-quality manufacturing method for fiber composite materials. Although the continuous filaments are impregnated with duroplastic resin by machine, trained staff are employed for the final processing in order to ensure outstanding quality during manufacturing.


The fiber matrix semifinished products impregnated with resin are called prepregs. The prepreg technique achieves the best possible strength values and the best possible manufacturing quality using the fiber composite technique when manufacturing structural components.


The technique is suitable for very highly stressed safety components within the fields of aerospace and racing. It is also becoming increasingly more important within car and truck manufacturing, with its high numbers of units.
