SCRIMP process This Seeman Composites Resin Infusion Process (SCRIMP) is described as a gas-assist resin transfer molding process. As an example glass fiber fabrics/ thermoset vinyl ester polyester plastic and polyurethane foam panels (for insulation) are placed in a segmented tool. A vacuum is pulled with a bag so that a huge amount of plastic can be drawn into the mold (Marco process approach). Its curved roof is made separately and bonded to the box with mechanical and adhesive fastening. It is similar to various reinforced plastics molding processes. 

RIFT or vacuum resin infusion is a hybrid of RTM and vacuum bag molding. In RIFT, one mold face of RTM is replaced by a flexible polymeric bag and resin is introduced into the mold by vacuum only. The process is better known in the USA as SCRIMP, which is a patented process. During resin infusion, the initial dry fiber compaction affects the permeability to resin flow and is time dependent, but when the resin enters the fibers, it appears to act as a lubricant and leads to further compaction. 

SMARTweave [82,83] is very useful for molding thick parts and can be used with RTM, SCRIMP , vacuum assisted RTM and other resin infusion processes.
