.... This may also result in a thicker part and improper fiber wet-out. The physical difference of the resins used for RFI versus VARTM or RTM is that the resin is usually in sheet or film form. Resins for VARTM or RTM may be one-component systems, containing the resin and catalyst/curing agent combined from...
