Composite vs. corrosion: Battling for marketshare

End-users who specify E-glass for tanks used in highly acidic (pH 3 and below) and highly basic (pH 10 or above) risk corrosive attack on the glass. In this micrograph, fibers in an FRP pultruded rod reinforced with Owens Corning’s (Toledo, Ohio) boron-free Advantex E-CR glass fiber shows no signs of corrosion after three months exposure to 10 percent sulfuric acid (see next photo for E-glass comparison).

Corrosion of metals, by some estimates, costs the U.S. economy $300 billion per year in maintenance, repair and replacement costs. Always an Achilles’ heel for manufacturers who work with metals, this massive problem plays to one of the composites industry’s greatest strengths. Corrosion prevention was one of the earliest applications for glass-reinforced plastics, championed by developers of highly corrosion-resistant isopolyester resin systems. Although that role has since been supplanted — especially in saltwater environments — by epoxy vinyl ester resins, manufacturers schooled in the use of composites continue to make inroads in several markets that have massive long-term potential.

One of the more lucrative strategies is refurbishing degraded municipal and industrial piping as aging infrastructure and postrecession budgets force maintenance decision makers in municipalities and industrial environments to look for options that are less drastic, disruptive and financially disabling than wholesale replacement.

Composites Advantage LLC (Laguna Hills, Calif.) offers a composite solution called Pipe Wrap Composite Strengthening. In the case of exposed or aboveground piping, sheet composite is wrapped around the pipe, acting as reinforcement for pipe walls that have been thinned by corrosive attack. Sheets of carbon fiber fabric are fed through rollers that apply a two-part proprietary epoxy to the material. The fabric is then directly wound spirally or in bands around the pipe. The epoxy, which has about a two-hour pot life, saturates the fabric and adheres to the metal substrate, bonding the carbon fiber to the pipe. The fabric is supplied by Edge Structural Composites LLC (Sonoma, Calif.). Steve Behrens, president of Composites Advantage, says higher-strength carbon fiber is better suited than glass fiber as a reinforcement for corroded pipe because glass not only has less strength, but, he claims, it also tends to elongate over time. Edge’s carbon fiber is certified to International Code Council (ICC) standards. The standard is mandated by most municipalities in California and requires, among other things, that the material pass a 20,000-hour durability test. Behrens says the company uses various sizes of carbon fiber fabric, but the most common is 18-oz unidirectional fabric, supplied in 25-inch/635-mm width.
