1. RecreationAutomotive Aerospace Industrial Inflatable World Leader in Braided Reinforcements QISO TM and Bimax TM Webinar May 9, 2012

2. QISO architecture Applications using QISO Why QISO Customization Cost/Properties Bimax Overview

3. Quasi-Isotropic Reinforcement in a Single Braid Layer Quasi-Isotropic Reinforcement in a Single Braid Layer Symmetric and Balanced with One Ply Symmetric and Balanced with One Ply 0° (axial) -60° (bias) +60° (bias) 33% Uniform Stiffness In All Directions

4. Applications

5. I-65 Bridge Repair Applications

6. QISO TM – Every Ply Balanced & Symmetric 1 layer braid 4 layers woven or 8 layers tape QISO allows for decreased layup time Reduced thickness, less weight 0/90 ± 45 0/90 ±45 Why QISO?

7. Symmetric & Balanced Lamina 1 layer QISO TM 0°, ± 60° Asymmetric & Unbalanced Laminate 2 layers fabric 0°,90°, ± 45° Why QISO?

8. QISO TM – 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?

9. Front Back Resistance to Crack Propagation (Velocity above penetration threshold) QISO TM arrests cracks with highly integrated multiaxial architecture Why QISO?

10. 33% Material Waste 19% Material Waste Plain Weave 52% Material Waste QISO TM Why QISO? (Reduced Material Scrap)

11. [0,+60,-60] Triaxial Braid [0,90] 8H Weave (QISO vs. Weave) TM Why QISO?

12. Woven Cone Why QISO?

13. Woven Cone

14. Why QISO?

15. QISO TM

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

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

20. (Hybrid Materials) Alternating Fiberglass & Carbon Fibers in Bias & Axial Positions Uniform Tool Surface – CTE is maintained with single balanced lamina Huge material costs savings & layup costs savings Customization

21. Fabric end-contouring Biaxial fiber -end domes Biaxial fiber -end domes Unidirectional + Biaxial fibers for hoop section Customization (Hybrid Architectures)
