The Kentucky Transportation Center’s research team has developed a new product called CatStrong CRP-X3 consisting of carbon fibre reinforced polymer rod panels (CRP) that are bonded to existing reinforced and pre-stressed concrete bridge structural members that have become deficient.
The goal of CatStrong CRP-X3 is to decrease bridge repair costs by reducing the number of labour hours typically required to retrofit concrete bridges.
CatStrong CRP-X3 is produced in the Structures Laboratory at the University of Kentucky. The research team, led by Program Manager Dr. Issam Harik, developed CatStrong CRP-X3 by using small diameter carbon fibre rods that are set on fiberglass mesh to form a sheet or panel. The “X3” in the title indicates the product strength level. According to the team, the CatStrong CRP-195 panel can resist more than 195,000 pounds of tensile force per one foot wide section, while weighing only 6.84 ounces per square foot. One square foot of CatStrong CRP-195 provides a strength equivalent to a square foot of A36 steel that is 0.28 inch thick and weighs 183.2 ounces (more than 27 times the weight of CatStrong CRP-195).
CatStrong has been installed successfully on four bridges in Kentucky since 2011. During the application of CatStrong CRP-X3, roads remain open, and the impact on the traveling public is minimal.
“The objective is to reduce repair costs since it can be quickly applied by a single person, thus reducing the labour hours and the construction equipment needed for the job. CatStrong CRP-X3 panels are ideally suited for structures with limited access, such as bridges over a waterway or a deep ravine,” said Harik.
Research to develop a revolutionary high-performance composite metal hybrid stabiliser bar for trucks and trains has entered a new phase. The findings from the project to date show that the technology has the potential to spin out into other sectors such as aerospace and could see the UK take a global lead with this disruptive technology.
COBRA International is collaborating with Flite, the Australian-based electric foiling surfboard manufacturer, on Fliteboard and Fliteboard PRO – two state of the art, electric foiling composite surfboards that reach speeds of up to 45kmh.
