Auxiliary Materials
Flow media, distribution mesh and drainage tubes
Infusion media and channels lower flow resistance so resin reaches a dry preform in the planned time. Drainage tubes and spiral wrap create controlled inlet, vent or vacuum routes.
In simple terms
Infusion media and channels lower flow resistance so resin reaches a dry preform in the planned time. Drainage tubes and spiral wrap create controlled inlet, vent or vacuum routes.
Best for
Vacuum infusion, VARTM and large dry-fibre preforms.
Watch out for
Flow media changes local resin flow and can print through or create race tracking. Distribution strategy must be designed for the part, fabric permeability and gel time.
Typical applications
Large marine, wind, industrial and structural infused parts.
