Manufacturing method of integrally formed aircraft seat leg, structure thereof and aircraft seat

A manufacturing method of an integrally formed aircraft seat leg, the manufacturing method comprising the steps of:

• A) taking a plurality of carbon fiber prepregs which have long fiber structure, a folding process being performed to the plurality of carbon fiber prepregs to make the plurality of carbon fiber prepregs preformed with stacking angles according to bends of an external shape of an aircraft seat leg;
• B) performing a cutting process to the plurality of carbon fiber prepregs that have gone through the folding process;
• C) performing a lay-up process by stacking the plurality of carbon fiber prepregs in a jig according to stacking design of the aircraft seat leg;
• D) performing a preforming process, in a mold, to the plurality of carbon fiber prepregs that have gone through the lay-up process;
• E) performing a thermal curing process by preheating and pre-pressurizing the mold with the plurality of carbon fiber prepregs, wherein the plurality of carbon fiber prepregs comprise thermoplastic material or thermosetting material, and then molding the plurality of carbon fiber prepregs by heating and pressurizing;
• and
• F) cooling down at room temperature and then removing the mold, thereby obtaining the aircraft seat leg, the aircraft seat leg being formed integrally and hollow in structure.
