Tow-preg filament winding production process

The tow-preg filament winding production process can be applied as an alternative to wet-filament winding. Research and production testing have shown the following advantages over wet filament winding:
1. Higher production speeds
2. Better laminate quality with lower weight
3. Healthier production environment
4. Less impact on environment

Cost analyses have shown that the process can be made competitive with wet-filament winding for large production quantities of carbon-epoxy pressure vessels. Other potential users that are targeted are filament wound carbon-epoxy drive shafts for the marine industry and filament wound carbon-epoxy refuelling booms, for the aerospace industry.

The tow-preg production process is applicable for any filament wound product, which requires a high quality laminate in combination with fast production. The initial material costs are a first barrier that must be overcome, but as the prices of carbon fibres themselves continue to increase, the tow-preg production process becomes even more lucrative.

At this stage the production process development is ready for direct application in production.
