Carbon Fiber Tank Repair

Repair leaking, corroded, or damaged tanks with durable, long-lasting carbon fiber

The benefits of repairing a tank with carbon fiber are endless, but the most important being that carbon fiber results in minimal to no downtime, effectively saving thousands of dollars in productivity loss. 

Tanks can fail for a number of reasons. RAK’s experience in industries ranging from Waste Water and Power to Automotive and Chemical, we’re able to provide durable, reliable solutions for corrosion, erosion, and structural reinforcement. 

For the most damaged, corroded, or eroded tanks, we’re able to offer a full structural composite system featuring carbon fiber composites. These composites are engineered to enhance the strength of the existing tank wall and take 100% of the structural load.


Carbon fiber is 70% lighter than steel, and 40% lighter than aluminum

Corrosion Resistance

While carbon fiber is open to oxidation at 450-degrees Celsius, the other materials it’s mixed with will determine if galvanic corrosion will occur. For example, aluminum is more likely to cause corrosion when mixed with carbon fiber. So, when possible, carbon fiber and Epoxy are used together in repairs. It is in that mixture that the corrosion becomes more determined by the Epoxy than the carbon.


The properties of carbon fiber are close to steel and the weight is close to plastic. This means the strength to weight ratio (as well as stiffness to weight ratio) of a carbon fiber part is much higher than either steel or plastic.

Application Flexibility

Carbon fiber is naturally light and can be extremely flexible when manipulated in the right way. In fact, carbon fiber composite can become flexible by as much as 88% as the temperature is increased.

Our carbon fiber composite repairs will meet the tough demands of your tank application. Whether it’s protecting structures exposed to aggressive environments or sealing hundreds of through-holes, RAK will save you significant money over traditional repairs or replacement.

What is carbon fiber, anyway?

To put it technically, carbon fiber is a long, thin strand of material composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size.

Carbon fibers come in many forms and can be manipulated based on a unique application need.
