A review on the mechanical properties of synthetic and natural fiber-reinforced polymer composites and their application in the transportation industry

 




The application of fiber-reinforced polymer (FRP) composites has achieved significant attention in the industry of transportation, specifically as metal substitutes due to a need for fabricating stable and fuel-efficient airplanes, vehicles, and ships. Excellent strength, resistance to corrosion, lightweight, and suitable fatigue endurance are some of the desirable properties that would encourage the use of FRP composites in the transportation sector. Polymer-based composite materials, combining the favorable properties of both polymer matrix and reinforcing fibers, can contribute to several excellent behaviors of the obtained material. Epoxy, polyethylene, and polypropylene are the primary polymer matrices used in FRP composites. The main reinforcing fibers incorporated in fiber-reinforced composites are made out of glass, carbon, basalt, hemp, or natural resources (e.g., sisal and jute). Due to high cost, low Young's modulus, low durability, and linear stress?strain behavior to failure of the FRP materials, which are used in transportation infrastructure, the objective of this review article is to study the recent aspect of reinforced polymers with a close focus on their mechanical properties in order to evaluate their application in maritime, automotive, and aerospace.

KU researchers explore FRP materials for dams, levee reinforcement

 


To address aging infrastructure, a team of researchers at KU is conducting research into repairing and retrofitting 700-plus dams, levees and related structures nationwide using FRP materials.

University of Kansas School of Engineering (Lawrence, Kan., U.S.) researchers are partnering with U.S. federal agencies in efforts to reinforce dams and levees across the U.S. using fiber-reinforced polymers, sensors, artificial intelligence and drones.

The five-year, $7.7 million project is a partnership between KU, the U.S. Army Engineer Research and Development Center (ERDC), the Department of Homeland Security’s Science and Technology Directorate and the U.S. Army Corps of Engineers (USACE).

The KU team of researchers is led by Caroline Bennett, Dean R. and Florence W. Frisbie Associate Chair of Graduate Studies, Glenn L. Parker Faculty Fellow and professor of civil, environmental and architectural engineering.

“The project focuses on developing repairs and retrofits for the inventory of concrete dams in the U.S., with an emphasis on efficient damage detection,” Bennett says. “In addition to repair methods, we’ll be using fiber-reinforced polymer materials, or FRPs, to address damage. Specifically, we’re targeting sliding at lift joints, restraining rocking between crest block and dam body during seismic loading, and damage on concrete spillways of dams. Our goal is to extend the usable lives of existing concrete dam infrastructure, which was mostly built in the 1930s and 1940s.”

Several of the dams and levees from this era have experienced catastrophic failures in recent years due to disrepair. A recent assessment concluded the nation’s dams and levees require $93.6 billion in upgrades to many of the 700-plus dams and related structures the USACE operates and maintains.

KU researchers are exploring new, safer approaches for assessing dam and levee damage, which traditionally required manual inspection. The team’s approach will rely on artificial intelligence, according to co-primary investigator Jian Li, Francis M. Thomas Chair’s Council associate professor of civil, environmental and architectural engineering at KU.

“My main role is focused on using deep learning and computer vision to autonomously identify the location and severity of dam damage, such as concrete cracking and spalling, for which FRP repair is needed,” Li explains. “Once the repair is done, these locations are no longer inspectable. Therefore, we’ll also develop self-sensing FRP repairs to enable continued monitoring of the repaired regions to ensure long-term safety. By leveraging emerging technologies including artificial intelligence, computer vision and advanced sensing, our research will greatly enhance timely repair, retrofit and maintenance of the nation’s large inventory of concrete dams.” 

In the meantime, work is underway by KU faculty, postdoctoral researchers, graduate students and undergraduate research assistants to identify fiber-reinforced polymer materials for use in concrete gravity dam applications. Materials characterization and large-scale testing is being performed at three different KU laboratories: the West Campus Structural Testing Facility, the Learned Hall Structural Engineering Testing Laboratory and the Lutz Fracture and Fatigue Laboratory

Rémy Lequesne, associate professor of civil, environmental and architectural engineering, says, “We’re developing more efficient methods for dam inspection and, through data collection and model development, providing tools that engineers can use to make decisions about whether and how to repair existing dams.”

Lequesne will oversee experimental testing of simulated joints in concrete dams, both with and without repairs. “Results will lead to recommendations and new modeling tools that engineers can use for assessment and design of repairs,” he says.

In addition, KU researchers will conduct a review of all research into FRP materials, with a particular interest in carbon-fiber-reinforced materials, to inform the project.

Materials & Processes: Fibers for composites

 The structural properties of composite materials are derived primarily from the fiber reinforcement. Fiber types, their manufacture, their uses and the end-market applications in which they find most use are described.




Glass fibers

The majority of all fibers used in the composites industry are glass. Glass fibers are the oldest and, by far, the most common reinforcement in most end-market applications (the aerospace industry is a significant exception) to replace heavier metal parts. Glass fiber weighs more than the second most common reinforcement, carbon fiber, and is not as stiff, but is more impact-resistant and has a greater elongation-to-break (that is, it elongates to a greater degree before it breaks). Depending upon the glass type, filament diameter, coating chemistry (called “sizing,” see “Critical fiber sizing," below) and fiber form, a wide range of properties and performance levels can be achieved.
