New High-Strength and High-Modulus Fiber Glasses

​​​​Ultra-long wind turbine blade and cost effective, high-pressure vessels can take the advantage of using high-modulus and high-strength of glass fibers, respectively. A recently patented glass system, RE2O3 (rare earth oxide)-MgO-CaO-Al2O3-SiO2, has presented commercial potentials addressing the above unmet needs [1, 2]. The new family of S-Glass derivatives enables fiber processing at lower temperature (TF at 100 dPa.s well below 1400oC) by using a standard E-CR Glass manufacturing technology, comparing with the traditional S-Glass fiber making process, which requires fiber drawing temperature near 1500oC or greater [3]. This presentation discusses RE-effects on mechanical properties, high temperature viscosity, liquidus temperature, softening and glass transition temperature [3, 4]. Mechanical properties of high performance glass fiber and its reinforced composites, UD laminate panel and high pressure vessel, are followed comparing with its counterpart of E-Glass fiber.
