20110014315 | In-mold decoration of composites manufactured by resin infusion between double flexible tooling system - A resin infusion system uses a housing that has an upper flexible diaphragm and a lower flexible diaphragm such that the two diaphragms form a cavity. A fiber reinforcement mat is positioned within the cavity as is an optional paint film. A mold is positioned below the lower diaphragm. A flow plate has a series of V-shaped grooves is positioned either underneath the lower diaphragm or overtop the upper diaphragm so that the grooves press into the respective diaphragm. A vacuum is created within the cavity causing resin to be drawn into the cavity with the resin interacting with the grooves increasing the turbulence of the resin flow. Once the reinforcement mat is properly wetted, a vacuum is created within the housing, the temperature is increased within the housing, the mold is pressed into the lower diaphragm while a vacuum is created within the housing. | 01-20-2011 |
