When FRP manufacturer Composite Advantage was asked to supply composite pile jackets for a waterfront application, it turned to nearby neighbor FiberSystems. “We specialize in very large FRP composite parts up to 100 ft. for bridge and waterfront infrastructures,” says Composite Advantage President Scott Reeve. “This was an application where the best approach was to source a pipe expert like FiberSystems.”
A New Zealand waterfront structure’s circular piers were eroding due to salt water, air and sun exposure. Concrete stay-in-place forms were used to repair the piers but corrosive conditions dictated the need for pile jackets for each of the piers. “FiberSystems had the mandrel sizes and the right manufacturing process to tackle the job,” says Reeve. “If a customer request falls outside our core competency, we’re able to use our network to meet that need.”
Twenty-four ounce fabric knitted from carbon and glass fibers, 50 in. wide by 17 ft. long, was hand laid up in two sections around mandrels 18 in., 20 in., and 24 in., in diameter. Once the sleeves were custom fabricated, they were removed and split lengthwise. The outer edge of one side of the cut and the inner edge of the opposing cut were pre-sanded to facilitate easy bonding. Once installed, a special mortar is used to fill the space between the FRP jacket and the concrete pillar, creating a corrosion resistant armor against the elements.
“It was a labor intensive process,” says Tim Morton, vice-president of operations for FiberSystems. “We had to adapt the process to meet the criteria needed to make the pile jackets. But we’re known as a fabricator’s fabricator. We are able to take a customer’s requirements and determine the best approach whether it means customizing processes or in some cases, creating new methods to complete a job.”
FiberSystems used unpigmented vinylester resin to produce a total of 17 18-in., inside diameter, five 20-in., inside diameter, and seven 24-in. inside diameter pile jackets. The FRP sleeves were shipped to New Zealand in October.
