World Leader in Braided Reinforcements QISOTM and BimaxTM Webinar May 9, 2012 Recreation Automotive Industrial Inflatable Aerospace
Overview • QISO™ architecture • Applications using QISO™ • Why QISO™ • Customization • Cost/Properties • Bimax™
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
Applications • I-65 Bridge Repair
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
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 QISO (Reduced Material Scrap) Plain Weave 52% Material Waste 19% Material Waste 33% Material Waste
Why QISO™? (QISOvs. Weave) TM [0,90] 8H Weave [0,+60,-60] Triaxial Braid
Why QISO™? Woven Cone
Why QISO™? Woven Cone
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 (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 Biaxial fiber -end domes Unidirectional + Biaxial fibers for hoop section
Customization (Tailored prepreg)
Customization (Tailored prepreg)
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
