PPG Industries Inc. (Cheswick, Pa.) focused COMPOSITES 2013 visitor attention on technical papers presented by its researchers, which described the company’s development of new E-glass fibers designed to improve fiber performance in a variety of structural and chemical environments. The new fibers are Hybon 2002 and Hybon 2026 XM, for structural applications, and Hybon 2002 and Hybon 2026 CR for corrosion-resistant and chemical applications. Each is said to exhibit higher modulus than previous E-glass products and is treated with an advanced fiber sizing that is intended to optimize interfacial adhesion with polyester, vinyl ester and epoxy resin systems. The new fibers enable rapid resin wetout and demonstrate better mechanical properties, particularly tensile strength and fatigue, says the company.
