Applications

QISOTM – Every Ply Balanced & Symmetric

1 layer braid4 layers woven or

8 layers tape

• QISO allows for decreased layup time• Reduced thickness, less weight

Why QISO™?

Symmetric & Balanced Lamina

1 layer QISOTM 0°, ± 60° Asymmetric & Unbalanced Laminate

2 layers fabric 0°,90°, ± 45°

Why QISO™?

QISOTM – Energy Absorption

• Stiffness mismatch at ply interfaces is eliminated thus reducing delamination stresses• Significant reduction in delamination enables improved laminate performance during impact events• Multiaxial laminate efficiently distributes load from primary impact location

Using QISO™ over changing cross-sections, there is:

• Reduced Concern Over Fiber Misalignment

• Simplicity In Design, Manufacturing, and Quality

Why QISO™?

• Widths To Optimize Utilization• Areal Weights / Thickness• Yarn Type• Hybrids• Fiber Orientation• Strategic Axial Placement
