The mandrel is foundational to filament winding. Its material (e.g., steel, aluminum, soluble plaster, inflatable bladders) and design directly affect tooling costs, manufacturing lead times, and the complexity of part demolding. Permanent mandrels offer longevity for high-volume production but incur higher upfront costs, while soluble or collapsible mandrels might be more economical for prototypes or complex geometries but introduce additional process steps for removal.
Precision in fiber architecture varies significantly based on a supplier's winding machine capabilities (e.g., 2-axis vs. 6-axis), control software, and their engineering expertise. For highly loaded or critical components, demand suppliers who can demonstrate tight tolerances on wind angles (often ±1-2 degrees), consistent ply thickness, and seamless transitions in complex helical or geodesic patterns. Lower-precision requirements for less critical components can be met by more standard equipment.
Wet winding, where dry fibers are impregnated with resin during the winding process, is generally more cost-effective for simpler geometries and larger parts, but can lead to higher void content and less consistent resin distribution. Towpreg winding, using pre-impregnated fibers, offers superior fiber-to-resin ratios, lower void content, and better mechanical properties, making it ideal for high-performance aerospace or pressure vessel applications, albeit at a higher material cost and requiring controlled storage conditions.
For CPVs, compliance with codes like ASME Boiler and Pressure Vessel Code Section X or DOT regulations (e.g., DOT-CFFC for gas cylinders) is paramount. For aerospace applications, AS9100 is standard, and NADCAP accreditation is often required for special processes such as composite fabrication (including filament winding), NDT, and heat treating/autoclave curing, ensuring rigorous quality and process control throughout the manufacturing lifecycle.
Internal quality validation often involves a combination of destructive and non-destructive testing. Destructive methods include coupon sectioning and micrographic analysis to measure actual fiber volume fraction, void content, and ply thickness. Non-destructive techniques like ultrasonic testing (UT) are used to detect delaminations, voids, or inclusions without damaging the part, especially critical for larger or flight-critical components.
Scaling up filament winding often introduces challenges related to consistency, cycle time, and material waste. Suppliers mitigate these by optimizing winding paths for efficiency, implementing automated resin mixing and delivery systems, investing in multi-station winding machines, and establishing robust quality gates throughout the production process. Thorough process validation and statistical process control (SPC) during pilot runs are crucial for a smooth transition.
