摘要： Methods and a double vacuum processing system are presented. A double vacuum processing system comprises a first vacuum zone; a second vacuum zone encompassing the first vacuum zone; a first vacuum pump connected to the first vacuum zone and configured to draw a vacuum within the first vacuum zone; a second vacuum pump connected to the second vacuum zone and configured to draw a vacuum within the second vacuum zone; and a diverter valve. The diverter valve is configured to alternate between pneumatically connecting the first vacuum zone to the second vacuum pump or connecting the first vacuum zone to the first vacuum pump.

摘要： A system for manufacturing a thermoplastic part from a blank part having a first moulding member and a second moulding member which are configured to cooperate together. A first heating body configured to heat the first moulding member and conductively heat the blank part. Two thermal insulation members are configured to cooperatively define a closed cavity in which at least the moulding members and the first heating body are arranged. A casing defining an internal volume in which at least the moulding members, the first heating body and the thermal insulation members are arranged, and a suction member is configured to lower the internal pressure in the internal volume to compress the preform part between the moulding members.

摘要： Systems and methods are provided for vacuum handling of composite parts. One embodiment is a method for performing vacuum securement of an object. The method includes covering the object with an impermeable membrane, locating a vacuum port at the impermeable membrane, and applying a negative pressure to the vacuum port that offsets air leaks between the impermeable membrane and the object.

摘要： A single stage OPF-to-carbon preform shape forming method includes positioning an oxidized PAN fiber preform with a female forming tool, positioning a vacuum bag over the oxidized PAN fiber preform, and vacuum forming the oxidized PAN fiber preform into a shaped body. The vacuum formed shaped body (while still in the shape forming fixture) may be loaded into a carbonization furnace and carbonized. The vacuum bag may be burned away in the carbonization furnace during carbonization.
