The VARTM process is applicable on larger, less complex and lower volume part
   production of composite parts
In the VARTM process, only a female mold is required with a vacuum drawn over the
   laminate through the use of a vacuum bag. Atmospheric pressure infuses the resin matrix
Design freedom is somewhat limited as compared to the RTM process
