Composite Materials Offer an Advantage to Bridge Building and Other Aspects of the Infrastructure Industry

Composite materials have long held an advantage in the Infrastructure industry over traditional materials such as wood, concrete and steel. While these traditional materials erode and require a certain amount of maintenance to ensure the structural integrity of the building is not compromised over time, composite materials are resistant to corrosion and provide more durability over an extended amount of time. For this reason, the Infrastructure industry has turned toward composite materials to build new structures and to repair older structures.


The two most common composites used in the Infrastructure industry: carbon fiber and epoxy

Of all composite materials used to strengthen the Infrastructure industry, the two most common include carbon fiber and epoxy. Carbon fiber is lightweight and features a high tensile strength, making it an ideal solution for many structures. It is also resistant to corrosion and is able to withstand high temperatures without losing strength.  

Likewise, epoxy is known for its strength and durability, as well as its chemical-resistance and ability to perform in high temperatures. Epoxy can also be customized to match the exact specifications needed for a project, including cure rate, water resistance and flexibility.


Composites are being used to rebuild the Sarah Mildred Long Bridge

Because of the advantages composite materials have compared to traditional materials used in the Infrastructure industry, the Maine Department of Transportation is turning to FRP composites to rebuild the Sarah Mildred Long Bridge, a bridge that connects Portsmouth, NH to Kittery, MA. This rebuild required a lightweight solution that was able to withstand the harsh winds and weather conditions that could impact the bridge.

In an interview with Composites Manufacturing Magazine about the bridge rebuild, Scott Reeve stated, “The product improves the aerodynamic performance of the span and eliminates the potential for undesirable dynamic responses.”
