Vacuum Assisted Resin Transfer Molding. Vacuum assisted resin transfer molding vartm is an affordable process that can be readily used for largescale composites structures. The vacuum assisted resin transfer molding process produces fiber reinforced plastic parts for various purposes.
During the vartm process a highly permeable distribution medium is incorporated into the preform as a surface layer and resin is inftised into the mold under vacuum. Vacuum assisted resin transfer molding vartm is likely the most common acronym of all used in the discussion of low pressure closed mold reinforced composite molding. However for many aircraft applications vartm does not currently provide sufficient repeatability or control of variability.
These fiberglass items have many applications in multiple industries.
