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™?
