SAERTEX LEO® SYSTEM
SAERTEX LEO is a composite system that fulfills the high fire protection requirements in the marine industry, the construction sector and in the production of rail vehicles. In contrast with conventional fire protection systems, LEO does not have a negative influence on the mechanical properties.
Depending upon the customer-specific requirements and intended application of the components, the LEO system uses different core materials, an optimized NCF layer (glass, carbon, aramid or hybrid) and special LEO infusion resins. A LEO protection layer is always the final component. The individual components are matched depending upon the intended application and client-specific requirements. They have no influence on the mechanical characteristics and the drapability of the textile is not limited. We supply the materials as a system for you to manufacture your parts and, upon request, also offer supporting services in the areas of engineering and manufacturing.
Benefits of SAERTEX LEO
- Fire Protection
LEO meets international fire protection standards, is IMO FTP and EN 45545-2 tested and conforms to DIN SPEC 91326. The composite system provides reproducible fire retardancy that is uniform across the entire component thanks to a low-viscosity, unfilled matrix, an intumescent protection layer and fire-retardant multiaxial non-crimp fabrics. This provides a uniform degree of fire protection across the entire surface of the component – for reproducible results. LEO is suitable for both monolithic and sandwich structures.
You can find a complete list of the flammability tests it has passed here.
You can find further information on the DIN SPEC 91326 for designers of rail vehicles here.
LEO is a lightweight material with excellent mechanical properties. Compared to conventionally produced components, LEO has convincing rigidity, tensile strength and bending characteristics that are many times better – despite its low weight and reduced material thickness. Cost-effectiveness is also a strong argument for LEO.

- Economic Efficiency
LEO offers maximum efficiency thanks to the lowest possible material input, a labor-cost-efficient manufacturing process (standardized infusion technology) and the production of components without time-consuming intermediate curing of individual layers. LEO is suitable for modern infusion technologies such as vacuum infusion. LEO can also be processed at normal room temperature. The entire techno-commercial cooperation is handled through a "single point of contact" with SAERTEX as your competent contact during all phases of the project.

- Precisely tailored SAERTEX product variants
Do you need precisely tailored SAERTEX product variants? No problem. According to your specifications and on the basis of individual CAD drawings, we will precisely pre-cut the respective shapes with our cutting machine and provide them to you for direct further processing. At SAERTEX there is no "waste". Our special nesting service ensures the most efficient use of your non-crimp fabrics during the cutting process.
To guarantee it stays in top form on its way to you, we develop customer-specific packaging concepts for our technical fabrics. This concept has been developed to the extent that customers can transfer the originally-packaged technical fabrics from the packaging and place them straight into the mold. There is no other way to achieve greater time – and therefore cost – savings.
- Toxicological Safety
LEO is free of halogens and toxicologically safe. No special protective clothing is required for processing. In the event of a fire, no toxic substances are released and smoke generation is minimal (57 x less smoke generation than with PES GFRP).
You can find a graph that shows the average smoke release rate according to ISO 5660 (m2/m2) here.
