3B fibreglass company have introduced a new E-CR glass roving specifically designed and formulated for acrylic resins allowing for the manufacture and production of glass reinforced polymethyl methacrylate thermoplastic composites.
The new combination of 3B’s optimised SE4740 glass reinforcement and TP resin system is fully compatible with existing equipment and manufacturing processes such as thermoplastic resin transfer moulding and vacuum assisted resin infusion with parts displaying mechanical properties similar to traditional thermoset composites.
The sizing for the new glass roving was developed in close collaboration with France-based partners Arkema, a world leader in the production of PMMA and Chomarat a foremost manufacturer of engineered fabrics. The resulting SE4740 roving provides excellent processability in both weaving and knitting procedures and outstanding compatibility with Arkema’s Altuglas acrylic resin system leading to excellent mechanical properties making it the recognised PMMA compatible roving available globally

3B Fibreglass believe Thermoplastic composites are well positioned against traditional materials in weight sensitive end-use applications in industries such as automotive, mass transit, aerospace and wind. The post-thermoformable nature and their consequent high recyclability make thermoplastic composites a cost efficient and an ideal solution for alternate sustainable and durable solutions.
