Continuous compression moulding process

Compounds are short (/w 0.3 mm) or long (> 0.6 mm) fibre reinforced thermoplastic or thermoset polymeric materials, which are processed automatically (injection or compression moulding), have good (mechanical) properties (for automotive, electric and electronic applications) and are relatively cheap. Composites contain continuous fibres (rovings, fabrics or mats), usually combined with thermosets, have excellent mechanical (structural) properties, but are very expensive because lack of an industrial process (mainly used in aerospace and aircraft industry). 

Mould filling is inherently more complex, due to introduction of compression driven flows. Preform flow resistance, or permeability, continuously changes through the compression flow stage. The balance of flow and preform related forces is complex, and is influential to processing times. How can these effects be efficiently modelled ...
