Cytec Industrial Materials (Heanor, Derbyshire, U.K.) is adding two new products to its rail portfolio that meet the fire requirements of EN45545-2:2013. The first, MTM 348FR, is a versatile curing epoxy resin prepreg matrix offering fire protection to category HL2. MTM348FR, in combination with either glass or carbon fibers, reportedly offers excellent mechanical performance and is ideal for the manufacture of lightweight composite components for interior and exterior structural and non-structural applications.

The second material, XMTM30, is a development product produced from a bio-renewable sustainable source and meets the requirements of category HL3. It is particularly suitable for the production of non-structural interior components. It can be used in combination with natural fibers to create a bio-sustainable system. Cytec is looking for partners and projects to develop this new technology.

Cytec emphasizes that the key advantage of prepreg technology is that it enables the manufacture of lightweight complex monolithic sections and sandwich structures, thereby offering weight saving and a reduction in running costs to the train operator. Typical railway interior applications include wall panels, window frames, partitions, archways, floors, ceilings, standbacks, luggage racks, seats and doors. All of Cytec’s prepreg resin systems are suitable for use with most formats and substrates including woven and uni-directional carbon and glass fiber.
