There are different trends in the civil engineering world like light weight, energy saving, safety, durability and low maintenance. Thanks to their unique combination of properties and ease of handling, our high-performance fibers Twaron and Technora provide solutions in a wide range of application areas and offer potential for different civil engineering products.
Strengthening of structures
The deterioration of concrete structures is demanding increasing attention around the world. Several repair techniques have been developed, and solutions often make use of Twaron and Technora. One widely adopted technique is column wrapping, whereby an aramid fabric is wrapped around concrete columns that need reinforcement. This is followed by resin impregnation and curing. Column wrapping is used for repairing old and deteriorating structures, and on structures that require additional reinforcement (e.g., to meet earthquake regulations).
To reinforce concrete structures, FRP rods based on Twaron or Technora fibers can be used as alternatives to conventional steel pre-stressing bars. In addition to excellent tensile mechanical properties, they offer superior corrosion resistance compared to steel. And thanks to the dielectric nature of aramid fibers, these rods offer additional advantages in cases where electrical conductivity is not allowed (e.g., to avoid electromagnetic interference).
Technora short-cut fibers are used to replace steel fibers in ultra-high-performance concrete – particularly in special situations where corrosion resistance and injury prevention are key requirements.
In masonry reinforcement, Twaron grid is used as an alternative to steel mesh. In addition to its mechanical properties, a Twaron mesh offers advantages over steel due to its easy installation, resistance to corrosion, and superior lifetime.
Due to its high strength, high modulus and good dimensional stability (low creep), Twaron offers unique solutions for the geotextile market – particularly in situations where traditional materials, such as polyester and polypropylene, do not meet the requirements.
Solutions that last
The industries we are involved in are constantly changing, and manufacturers are facing increasingly stringent market demands. That’s why we continue to develop our technology, our products and our processes. To a major extent, sustainability is the foundation of the composites industry: composite products offer the combination of light-weight and good mechanical properties, often replacing steel or concrete solutions, resulting in fuel savings as well as reduced maintenance costs. Waste aramid can often be reclaimed and recycled for other applications.
