Magnetically Controlling Permeability in a Vacuum Infusion Process

Detailed Technology Description: One issue associated with thevacuum infusion resin transfer (VIPR) process, is that flow control is based onthe ability to manipulate the permeability of the VIPR chamber, which requiresan air-tight contact surface between the chamber and the flexible moldsurface. This may be difficult where theareas of the composite structure are irregular or not flat. A method of preform relaxation which does notrequire direct contact with the mold surface may be a simpler solution tomanipulate permeability rather than designing a special VIPR chamber. Using a magnetic field to stretch theflexible molding surface and relax the fabric can potentially replace the VIPRchamber while not requiring direct contact or an air-tight seal.
