Developed within mRT, CVR (glass-resin composite) reinforcement has been designed to meet the high demands of industrial sectors where material performance and reliability are crucial, particularly in the field of tyres subjected to severe conditions. Reinforcements play a key role in the functioning and durability of these applications and can be made from a wide variety of materials depending on the mechanical and environmental constraints.
Manufacturers today face the challenge of finding a reinforcement that combines good compression resistance, controlled elongation, high fatigue resistance and long-term dimensional stability. This balance of performance remains rare on the market, even as production rates and quality requirements continue to increase.
To meet these challenges, mRT developed the CVR from an optimised glass-resin composite. The aim was to design a modular reinforcement capable of adapting to a wide range of mechanical, thermal and chemical stresses. The teams worked together on the reinforcement geometry, composite formulation and manufacturing parameters to obtain a high-performance material while maintaining high industrial production rates. This comprehensive approach allows the properties of CVR to be finely adjusted according to specific specifications.
The CVR reinforcement is the result of combining high-performance glass fibres with a carefully selected resin matrix. Its dimensions and characteristics can be adapted to meet specific requirements in terms of rigidity, thickness, thermal behaviour and production speed. The material has been designed to remain stable under compression, withstand prolonged fatigue cycles and offer controlled elongation. In addition, ongoing developments are paving the way for more sustainable or multi-material variants to meet enhanced performance or environmental impact objectives.
CVR offers numerous benefits. It provides high-performance, highly adaptable reinforcement, with measurable gains in terms of component longevity, reduced fatigue-related failures and increased stability in harsh conditions. Its modularity also opens up applications in many industrial fields where high performance is expected, while optimising production rates.
Through the development of CVR, mRT demonstrates its ability to design innovative, modular reinforcements that meet current and future performance requirements, paving the way for new generations of composite solutions adapted to the industrial challenges of tomorrow.
