Abstract
A method of welding together graphite fiber reinforced thermoplastic laminates. The process allowing immediate application of graphite thermoplastic materials for the building and assembly of primary and secondary structural parts used with aircraft airframes and similar structures.
Claims5
A method of welding together parts formed of graphite-fiber reinforced polyetheretherketone laminates, comprising the steps of:
- disposing two said parts in surface contact between a pair of opposed electrodes;
- applying pressure through said electrodes to the area of said surface contact;
- applying voltage and amperage across said electrode sufficient to soften the polyetheretherketone in surface contact between said electrodes;
- and
- cooling said parts in said surface contact to form a weld.
