8 These versatile polymer materials immediately found acceptance in aerospace, construction, transportation, the infrastructure, and industrial process equipment, where their unique properties brought value and new solutions to the practicing engineer. Because of its superb corrosion resistant properties, composite fiber reinforced plastic (FRP) has displaced other more costly metals in many industrial process equipment, tanks, piping, duct and hood systems, reaction vessels, etc. Because of its fast cure, polymer concrete has displaced Portland cement concrete in highway bridge deck overlays where traffic can resume within hours instead of a week. Special resins using advanced thickening technology have revolutionized the rehabilitation of municipal and industrial process sewers using cured-in-place pipe (CIPP). However, the availability of good engineering information and data regarding composites has not kept pace with the advances in the technology.

9 Reichhold s FRP Technology Guides Series, of which The FRP Materials Selection Guide is a part, is intended to give practicing engineers an understanding of composites technology in order that they may be able to effectively incorporate FRP, polymer concrete, and other polymer materials in their designs. The Materials Selection Guide is a step-by-step Guide to selecting resins for use in these applications. Resin Selection is different for the corrosion barrier than for the structural laminate. This Guide focuses the resin Selection for the corrosion barrier and the structural laminate. CORROSION HOTLINE Chemical attack will alter the structural performance of laminates and environmental effects must be considered in the Selection of an appropriate resin. Reichhold provides technical assistance for the Selection of the proper resin and will provide test coupons prepared according to ASTM C-581 for in-plant testing.
