  1. World Leader in Braided Reinforcements QISOTM and BimaxTM Webinar May 9, 2012 Recreation Automotive Industrial Inflatable Aerospace

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

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

  4. Applications

  5. Applications • I-65 Bridge Repair

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

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

  8. 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

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

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

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

  12. Why QISO™? Woven Cone

  13. Why QISO™? Woven Cone

  14. Why QISO™?

  15. Why QISO™? QISOTM

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

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

  18. Customization

  19. Customization

  20. Customization (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

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

  22. Customization (Tailored prepreg)

  23. Customization (Tailored prepreg)

  24. Cost

  25. QISO Properties • Significant material characterization done in various research efforts • Several epoxy systems tested (PR520, 3502, 5208, 862/W), Vinyl Ester (Derakane 411) and Phenolic • Primarily in-plane properties at room temperature • Detailed data can be supplied upon request
