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

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

Applications

Applications I-65 Bridge Repair

Why QISO™? QISOTM – Every Ply Balanced & Symmetric 0/90 ± 45 0/90 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) Front Back QISOTM arrests cracks with highly integrated multiaxial architecture

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

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

Why QISO™? Woven Cone

Why QISO™?

Why QISO™? QISOTM

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

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

Customization

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

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

Customization (Tailored prepreg)

Cost

QISO Properties • Significant material characterization done in various research efforts • Several epoxy systems tested (PR 520, 3502, 5208, 862/W), Vinyl Ester (Derakane 411) and Phenolic • Primarily in-plane properties at room temperature • Detailed data can be supplied upon request
