AGY Introduces New Glass Fibre with Unprecedented Tensile Modulus Level

AGY has introduced a new glass fibre with an unprecedented tensile modulus of 99 GPa (14,359 ksi) – a level they say is not previously seen in commercial glass fibre products. 

Called S-3 UHM glass, this ultra-high modulus material was developed using AGY’s advanced Modular Direct Melt (MDM) production technology and utilises a unique formulation of S-Glass raw materials to develop the mechanical properties.  According to AGY President, Drew Walker, “The creation of our improved fibre manufacturing technology coupled with an in-depth understanding of the constituent chemistries enabled us to develop this new material which increases the tensile modulus by 40% above that of traditional E-Glass fibres.”

The new material will allow designers and manufacturers to use glass fibre reinforcement in areas previously limited to other types of fibres.  “It is an exciting opportunity for our customers,” continued Walker. “It brings a new level of tensile modulus to the arena of glass fiber without losing any of the unique properties that glass brings as a component of composites such as electrical and thermal insulation, and high impact absorption and low coloration of the resin system.”

Commenting on the rapid growth of the company’s range of available fibres including the recent introductions of S-1 HM rovings, S-3 HDI yarns and L-Glass yarns, Walker said “It shows how AGY is developing glass technologies to meet the demands of the marketplace and highlights our ability to translate customer needs into products in the glass fibre arena.  Our new S-3 UHM glass fibres will be a unique fibre in the market, offering a new level in the ability of glass fibres to meet the demands of a broad range of applications.”

S-3 UHM is available in a range of different formats including yarns, rovings and chopped fibres.
