Why Specify?

Composites offer many advantages compared to traditional materials used in corrosion applications.

  • Corrosion Resistance: FRP composites do not rust or corrode. There are various resin systems available to the fabricator which provide long-term resistance to almost every chemical and temperature environment. Properly designed FRP composites parts have long service life and minimum maintenance as compared to most competitive materials.
  • Inherent Durability: There are case histories of fiberglass ductwork being in service in chemical manufacturing plants for over twenty-five years – operating in harsh chemical environments twenty-four hours a day, seven days a week. How long do composites last? In many cases, over fifty years and still counting!
  • High strength: FRP (Fiber Reinforced Polymer) composites are very effective in providing high strength components. FRP composites can be designed to provide a vast range of mechanical properties, including tensile, flexural, impact and compressive strengths.  FRP composites are not isotropic, but anisotropic which allows the designer/fabricator to design a laminate with oriented reinforcement to provide strengths in specific areas or direction as the final application requires.
  • Lightweight: FRP composites have a higher specific strength than many of the materials used in corrosion applications. They can deliver more strength per unit of weight than most metals.
  • Design Flexibility: FRP composites can be fabricated into virtually any shape a designer may have in mind. A corrosion application can be complex or simple in configuration; large or small; structural, decorative or cosmetic , or all inclusive. FRP composites free designers to try new concepts, from prototype to production.
  • Elevated temperature service: FRP composite parts fabricated utilizing resins and inert filler technology perform very well in elevated temperature applications.
  • Thermal cycling: FRP composite parts, in large part due to the polymer matrix selected,  operate in applications that experience temperature changes of more than 150º F for extended periods of time without adverse effects.
  • Dimensional Stability: FRP composites maintain their shape and functionality, even under severe mechanical and environmental stresses. FRP composites typically do not exhibit viscoelastic or “cold-creep” characteristics of thermoplastics. The yield point of FRP composites is generally its break point.
  • High Dielectric Strength: FRP composites have excellent electrical insulating properties, making them an obvious choice for current carrying applications.
  • Parts Consolidation: FRP composite parts often have replaced assemblies of many parts and fasteners required for traditional materials such as stainless steel.
  • Ability to Form Shapes: FRP composites can be formed into complex shapes easier than other competing materials. This ability gives the designer/fabricator the freedom to create any shape or configuration.
