PROCESSES

1

VARTM-RESIN INFUSION PROCESS

The VARTM acronym is applied to the process of "Vacuum Bagging Infusion", that is where the composite is molded using a rigid mold to provide part geometry and a thin flexible membrane over the fiber, with outer atmospheric pressure compressing the fiber tight against the rigid mold surface.

 

2

WET LAYUP

The wet lay-up process can be Vacuum Bagged or open cured. The fibers are positioned in the mould dry and the resin is applied with a brush. The resin is mixed by hand and mistakes can be made during mixing. This is a relatively inexpensive process, but normally the part is heavier and the fibers can distort during the lamination process meaning the process is less controlled.

3

PREPREG

Prepreg is composite materials, such as carbon fiber or EGlass, that have been pre-impregnated with activated resin. The resin system is almost exclusively epoxy resin, which has been mixed with its hardener at the manufacturing stage, before being impregnated into the dry reinforcement fabric to make the ‘prepreg’ reinforcement. It is then Vacuum Bagged onto the mold.
