Method of Impregnation
- Production speeds of up to 100 ft./min.
- Increased heating zone
- Heating zone has increased from 3/8″ wide squeeze point at nip roll to 75″ wrap around four rolls.
- Resin flow time has greatly increased, thus allowing more time for full impregnation
- Wider range of materials can be processed
- Unidirectional tapes.
- Woven fabrics up to 1000 g/m2.
- Woven fabrics with 0°, 90°, +45° bias.
- Needle punch carbon fiber mats.
- Efficiency and consistency
- With no squeeze point there are no hydraulic forces (resin damming) acting on the fiber to distort weave, create voids or gaps, or to change width of product.
- Accurate and consistent AFW (Areal Fiber Weight).
- Does not disturb finished product width and thereby decreases waste.
- Lower costs
- Labor no longer needs to be specialized.
- With low carbon fiber elasticity the paper does not stretch and is allowed to massage the resin into the fiber bundle.
- Does not force the resin into the fiber bundle, thereby destroying the preconditioned parameters such as film (resin) weight and film spread.
- Creates a carbon paper-like finish on final product that is highly desirable in such industries as sporting goods.
- Eliminates hairline cracks in Prepeg.
