Pre-preg tapes are generated via two processes, tow-preg and slitting of pre-preg sheets. Tow-preg lines combine a number of Cygnet Texkimp core skills and products.
- Unwinding: of paper, films, and filaments
- Thermal Treatment
The following highlights the difference between tow-preg generated online and tow-preg tape generated by pre-preg slitting:
- Tow-preg lines endeavor to achieve a similar outcome to slit pre-preg tape through fewer process steps. With tow-preg, the storage of intermediate β-Stage pre-preg is eliminated. The tow-preg yields the equivalent of a pre-preg slit tape
- Similar to full industrial scale pre-preg lines, areal weight of the pre-preg and percent infusion, measure in weight percent resin and weight percent fibre, are the critical performance parameters.
Cygnet Texkimp has supplied tow-preg and pre-preg slitting lines of single end to multiple end designs. Our 4 end slitting pilot line is frequently considered by our clientele.
