JEC Europe 2013 - Based on low-density PUR foam reinforced with a 3D glass structure, SAERfoam is ideal for many projects.

Based on low-density PUR foam reinforced with a 3D glass structure, SAERfoam is ideal for many projects. Using vacuum infusion or RTM, this reinforced core provides a structural sandwich laminate. By creating the correct density of “bridges” in both directions of the sheet, one can optimise the mechanical properties of the structure to achieve the best performance-to-weight ratio, offering a very cost-effective solution. Custom finishing, for instance supplying the core with grooves or as a kit, is also possible.

With 45°reinforcement in two directions, the SAERfoam O grade creates ideal properties for multi-directional loads. This core easily replaces any existing material currently on the market, such as PVC, PET, etc. The high strength-to-weight and stiffness-to-weight ratios make SAERfoam O ideal for marine applications such as decks, hulls, and floors in transportation applications. The material has been certified by Bureau Veritas and is undergoing testing by Germanischer Lloyd, due for completion in 2013.

The X grade is ideal for highly oriented structures, such as bridge decks in civil engineering. Due to its 3D glass structure, the high rigidity of SAERfoam provides excellent stiffness and buckling resistance. Main applications currently include industrial vehicle bodies and civil engineering fittings. SAERfoam can be used with most available resins, such as epoxy, vinylester, etc. with the added benefit of excellent fatigue properties compared to existing foam cores.
