E-Glass Yarn Sizing System targets aerospace industry.
Press Release Summary:
January 6, 2011 - Initially available on DE75 yarn, 947 direct sizing system for E-Glass yarns provides aerospace customers with opportunities to remove weight from traditional composite products while increasing tensile and compressive strengths. Fibers with 947 sizing can be woven into fabric and used in composite applications without additional finishing, eliminating related fabric integrity erosion. Currently, 947 sizing is compatible with epoxy and phenolic resins as well as thermoplastics.

AGY Announces New Direct Sizing System for E-Glass Yarns Used in the Aerospace Industry
Press release date: January 3, 2011
Building on its experience with its S-2 Glass® direct-sized products, AGY developed the new sizing system, called 947, for yarns used primarily in aerospace applications. Fibers with 947 sizing can be woven into fabric and used in composite applications without additional finishing.
Yarns produced with the new 947 sizing have significantly higher tensile strengths than their counterparts coated with traditional oil and starch sizes. And, because fabrics made from 947-coated yarns need not undergo the damaging heat treatments or other cleaning processes that can erode fabric integrity, they can contribute considerably more strength to the composite materials into which they are incorporated.
Uni-directional standard general purpose epoxy laminates manufactured with this fiber have an ASTM 3039 tensile strength of 200 ksi (1379 MPa), a 40% improvement over traditional E-Glass yarns; and an ASTM D3410 compressive strength of 125 ksi (862 MPa), a 45% improvement over traditional E-Glass yarns.
"This new sizing system will provide our aerospace customers with new opportunities to remove weight from traditional composite products," said Drew Walker, AGY Vice President of Sales and Marketing. "947 has been developed for a wide range of applications. It is compatible not only with epoxy and phenolic resins but also with thermoplastics. It even has the potential to be used in the development of hybrid glass and carbon fiber fabrics."
The new sizing system is initially available on AGY's DE75 yarn that is used primarily in aerospace fabrics and will soon be offered in other yarns as well. For more information, please visit www.agy.com.
