Gordon Composites™ GC-70-ULZ

About
Made with high strength glass fiber commonly called “S” glass, this unidirectional glass laminate provides strength and fatigue resistance superior to laminates made with standard “E” glass. GC-70-ULZ is manufactured with a proprietary pulforming process in which all glass fibers are pretensioned and aligned during the impregnation and curing process.&&

Notes
1. Width: .1.50″ to 8.75″ Thickness: .020″ to .040″ Length: 6″ to 120″
2. Typical properties: these are not to be construed as specifications.
3. 90 degree orientation
4. 0 degree orientation
5. Strength Values developed from ASTM D790 are dependent on thickness. As thickness increased flex strength decreased. The test data above is based on a test thickness of .060″
6. Inter-laminar, 2,3 direction
7. In-plane, 1,2 direction
8. nu12 (0/90), valid both tensile and compression
