Specialist & Toll
Narrow tape prepreg.
Specialty narrow formats for AFP/ATL, filament winding, and engineered structures — processed from your fibers and resins on CDI narrow-tape capability.
The problem with traditional supply
- High minimums that do not fit development or specialty programs
- Long lead times and cold-chain / inventory burden for perishable prepreg
- Slit-tape logistics, edge waste, and “best fit” rolls that do not match the process
- Limited ability to protect or iterate proprietary resin systems
CDI approach
Customer-supplied inputs, specialty impregnation, and formats matched to the manufacturing method — with optional migration to in-house CD6019 / OnDemand equipment.
| Format | Dimensional control | Shape tolerance | Winding | Typical use |
|---|---|---|---|---|
| Towpreg | Low | N/A | Cross wound, no backer | Filament winding, pressure bottles, tubulars |
| Precision Tow | Medium | ±0.008″ | Parallel wound with backer | High-pressure cylinders, engineered structures |
| ShapedTape | High | ±0.003″ | Parallel wound with backer | AFP/ATL, machine-paced winding |
Tolerances are illustrative brochure figures from the July 17 demo. Fiber size classes commonly discussed: roughly 6k–60k. Resin families include hotmelt epoxy, toughened systems, BMI, cyanate ester, and other specialty chemistries subject to process review.
Equipment counterpart
The same specialty formats are supported on CDI narrow tape equipment for customers who graduate from toll to in-house production.
