Fabric Composition: Should you use carbon fiber or fiberglass repair systems?

Posted by: Casey Whalen

Every composite repair has the capability to work when designed correctly and installed properly. Some systems are designed with particular objectives in mind, whether external corrosion, mechanical damage, leak repairs or another issue.

Composite repair systems have proven to be the most cost effective solutions for these designs. Other systems are designed and sold as an all-purpose repair, without consideration for individual aspects. Regardless of the system used, it is imperative that the design of the repair is in accordance to current standards and that proper due diligence is performed to ensure all scenarios are accounted for including substrate properties, defect type, chemical resistance, temperature ratings, installation conditions and surface preparation.

There are many differences between Pipe Wrap products. We’ll begin by addressing the fabric composition of our three main products.

FormaShield – Fiberglass

A+ Wrap – Fiberglass

Atlas – Carbon Fiber

There are several differences between carbon fiber and fiberglass, which are compared in the graphic below. Note that within each fabric type there are multiple categories as well such as E-glass, S-glass or C-glass for “fiberglass,” so generalities are given.


Carbon fiber repairs will typically be thinner than fiberglass to achieve the same load-bearing capability but may also cost more. If the pipe is cathodically protected, it may require an insulating layer of fiberglass to separate the pipe from the carbon fiber.
