Reinforcements for Composites Solutions for Closed Molding Fire Resistant Rovicore™ FR (Fire Resistant) complements the Rovicore™ range in providing a solution geared towards the manufacture of composite parts requiring fire resistant characteristics. DESCRIPTION Rovicore™ FR contains a porous draining core with two layers of fibreglass mats which are mechanically assembled and cut using stitching. Its distinguishing feature lies in the fact that its core has been designed without using halogen products. PROCESS As with all the products in the range, Rovicore™ FR is specifically adapted to closed mold procedures, namely RTM, RTM Light. The specific construction of its core makes it of particularly high-performance for low pressure injection methods. MARKETS • Rolling Stock (train, underground rail networks, tramway) • Building and construction • Industrial elements requiring fire resistance ADVANTAGES The changes made to the Rovicore™ FR core do not alter its properties in any way, preserving all the advantages from the Rovicore™ range: ➜ Good levels of deformability and elongation allowing for easy reduction of angles and the manufacture of complex elements. This is not the case with some products made from 100% glass. ➜ Resilience and compressibility of the core allowing for Rovicore™ to adapt to the different thicknesses of composite parts. ➜ Excellent permeability of the synthetic core facilitating rapid creep even in the case of a heavily filled resin. - No filtering of loads - Homogeneity throughout the entire reinforcement. All these advantages mean gains not only in terms of time but also in terms of cost.

Fire Resistant The main purpose of ROVICORE™FR lies mainly in its behaviour in response to fire which contributes to the possible granting of the HL3 rating in accordance with the new norm NF EN 45 545. This new European norm regulating the railways should come into force in 201 6. Testing undertaken by certified laboratories on the composite parts com- bined with different types of resins have proven the effectiveness of using TEST RESULTS Evaluation of molded parts according intumescent resin and ROVICORE™ FR Lateral spread of flame - ISO 5658-2 Textiles Industries North Africa North America...
