Fibrwrap Construction recently used its Tyfo Fibrwrap composite system in the recent restoration of Miami’s Grove Isle Bridge.
The rehabilitation project included the retrofit of fibre reinforced polymers to the structure's columns, beams and slabs. In addition to Fibrwrap repairs, Fibrwrap Construction tackled concrete restoration and epoxy crack injection to further strengthen and stabilize the bridge.
Manufactured from glass, carbon, aramid and hybrid fabrics, Tyfo Fibrwrap are held together by TYFO polymers. The company's advanced, high-strength fibre products are specially engineered to repair and restore bridges, buildings, piers and pipelines, offering cost-effective, turnkey repair options for many industrial projects.
The repairs of Grove Isle Bridge were deemed necessary by inspection engineers after discovering corrosive damage to the structure's reinforcing steel.
""We've performed over 6,000 structural upgrades and retrofits since 1988,"" says Fibrwrap Construction CEO Heath Carr. ""Using our innovative composite retrofits, it was our goal to restore the strength and integrity of the bridge while limiting interruptions to the flow of Grove Isle employee and tourist traffic.""
Now that Grove Isle Bridge repairs are complete, the bridge's structural health will be monitored over the next year by students and researchers at the Universities of Miami and Cincinnati.
To initiate this innovative new assessment program, wireless sensors were placed at strategic points along the rehabilitated bridge. By recording vibrations, acoustic wave data and concrete alkaline levels, researchers can detect the presence of cracks and deficiencies that may affect the bridge's future durability.
This new emission technology is intended to help bridge owners and transportation departments monitor and predict future structural problems, alerting them to the need for critical repairs and upgrades.
Covestro is pushing ahead with developing and marketing its continuous fibre reinforced thermoplastic (CFRTP) composites by introducing Maezio as brand name.
Shape Machining has pressed the first batch of parts that combine short fibre sheet moulding compound (SMC) over an optimised, long fibre carbon ShapeTex preform.
3M is adding Scotch-Weld Multi-Material Composite Urethane Adhesives DP6310NS and DP6330NS to its portfolio of structural adhesives. These products are designed for lightweight assemblies in trucks, buses, RVs, speciality vehicles and passenger rail, and other markets like sporting goods and panels.
