One aspect of fiberglass products that requires careful consideration is abrasion resistance. By introducing additives such as silicon carbide or aluminum oxide to interior surfaces, FRP can be significantly reinforced to withstand abrasion — particularly effective in mixing tanks up to the agitator level, inlet piping for desalination plants, splitter nozzles and similar applications.
Nine ways to improve abrasion resistance
- Urethane-modified resins such as Derakane 8084 or Derakane 441.
- Abrasion-resistant additives (silicon carbide, aluminum oxide) in the corrosion barrier — the area most susceptible to wear.
- A Kevlar veil for added durability.
- Thermoplastic liners (polypropylene, PVC, PTFE) for wear resistance.
- Replaceable wear plates or swappable sections of pipe/equipment for easy maintenance.
- Different-colored wear layers that serve as a visual indicator of wear.
- A regular program to reline wear areas, extending product life.
- For ductwork, “flooded elbows” so abrasive air impacts water rather than the material directly.
- Flow-altering design changes — the malleability of FRP allows complex shapes without expensive tooling.
Fortifying fiberglass products for abrasion resistance is a strategic approach that notably improves durability and operational efficiency across a wide array of uses. Explore our FRP ductwork & piping or talk to our engineers.
