VARTM – Vacuum Assisted Resin Transfer Molding

Vacuum Assisted Resin Transfer Molding, or VARTM, provides as a solution for more intricate parts such as radiused and flat pole collars, surge rings, flange rings, fan baffles, stator end caps, flat discs and rings. VARTM molded composites are provided where both mechanical and dielectric strength are required in complex shapes and surfaces. Temperature ratings currently include 130°C and 155°C (Class B and F).

The Gund Company has the capability to produce a wide variety of custom geometric shapes and sizes via the VARTM process. Additionally, the composite resins and fabrics can be varied to meet the needs of the application. Examples of this could include the use of different types of fabrics and reinforcing fibers such as an S-Glass, Carbon fiber or Kevlar to create higher strength composites in complex shapes.

VARTM also provides fiber orientation contoured to the shape of the part. If a part is machined from flat composite sheet, fibers are only oriented in the x-y plane, which can create week spots in a 3-D contour.
