Glass fiber manufacturer China Jushi Co. Ltd. (Hangzhou, China) introduces its E9 ultra-high-modulus glass fiber with improved mechanical properties. With a modulus of more than 100 GPa, this new, high-performing fiber is said to create more opportunities for the expansion of glass fiber-reinforced composites into high-end applications.

E9’s modulus is said to be 36% greater than traditional E-glass, and 12% greater than Jushi’s E7 glass. Jushi says this translates into a 60% strength increase compared to E-glass, and a 12% strength increase compared to E7. Additional product benefits include improved high-temperature resistance, with a softening point 132ºC higher (970ºC) and a coefficient of thermal expansion (CTE) 21% percent lower than traditional E-glass; increased fatigue and impact resistance; and boron- and fluorine-free glass composition for an environmentally-friendly production.

E9 glass fiber is suitable for use in a variety of end markets, including wind, infrastructure, transportation, aerospace and more. Typical applications include large wind blades, optical cable reinforcement, aircraft parts, automotive components, temperature-resistant parts and sport equipment. E9 is currently still undergoing formulation testing.
