Towpreg Lab Scale – ERMES

The TOW-PREG has been designed for impregnating dry tow coils with resin, equipped with a unit for unwinding dry tow fiber coils, an impregnation unit with two interchangeable modules for working with thermosetting and thermoplastic resins, and a rewinding unit with temperature and humidity control.
The improvements achievable with this solution compared to technologies currently available on the market are:

1. Up to 50% reduction in production costs compared to the
   use of slit-tape, thanks to the absence of slitting, the
   possibility of implementing “just-in-time” management to
   avoid the costs of long periods of storage in refrigerated
   warehouses, and the high maximum process speed,
   estimated at around 200 m/min.
2. High reliability, repeatability, and quality control of the
   material in terms of fiber/matrix ratio and therefore uniform
   and controlled properties in the final tank, thanks to the
   automatic feedback system based on in-line grammage
   control sensor and the neural network integrated into the
   machine software.
3. Possibility to reduce safety factors adopted in tank design,
   thanks to improved control of the production process.
4. Ability to process resins critical from the perspective of
   viscous behavior, thanks to the progressive heating system.
