Why QISO™?
QISOTM – Every Ply Balanced & Symmetric

1 layer braid
4 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
Why QISO™?
Resistance to Crack Propagation
(Velocity above penetration threshold)

Why QISO™?
Using QISO™ over changing cross-sections,
there is:
• Reduced Concern Over Fiber Misalignment
• Simplicity In Design, Manufacturing,
and Quality
