Materials path
Send fiber and resin. Get a roll you can test. Then decide whether to own the line.
CDI, a leading global supplier of prepreg machines and specialist composite processing equipment, runs the same process on toll that it sells as a CD6019.
- 01 Send the chemistry
Fiber and matrix. Development quantities. 500 g of matrix is enough to start.
- 02 Run it on the process that would ship
Impregnate, form, wind. Same dies, same recipe logic as in-house.
- 03 Take the roll. Keep or install
Unused matrix is returned. If the recipe holds, the next step is a CD6019 or an OnDemand module — not a new invention.
Formats
Four ways the material shows up.
| Format | What it is | Edge | Wind | Backer | Best fit |
|---|---|---|---|---|---|
| ShapedTape | Narrow tape at final width | Formed. No cut edges, half-tows, or fuzz | Parallel | Poly film | AFP / ATL drop-in for slit tape |
| Precision tow | Impregnated tow, higher speed | Medium dimensional control | Parallel | Poly film | Winding and lower-cost AFP/ATL |
| Towpreg | Impregnated tow, no paper | Lower dimensional control | Traverse | None | Filament winding, pultrusion |
| Narrow tape prepreg | Toll on a CD6019-class line | Formed or specified with the order | As specified | As specified | The format that most often becomes an in-house line |

Bridge
Toll is not a dead end.
The roll is made on the process a shop would buy.
