Abstract
Systems and methods are provided for fabricating composite parts. One embodiment is a method for fabricating a composite part, the method comprising: reducing a bulk factor of chips of chopped fiber while forming the chips into a pre-consolidated charge; shaping portions of the pre-consolidated charge into shaped volumetric charges that fit within a die; and compression molding the shaped volumetric charges within the die.
Claims20
A method for fabricating a composite part, the method comprising:
- reducing a bulk factor of chips comprising chopped fiber while heating, to a temperature between six hundred and eight hundred degrees Fahrenheit, and forming the chips into a pre-consolidated charge;
- separating portions from the pre-consolidated charge;
- placing a portion of the portions into a receptacle within a die, wherein the portion has a mass equal to the composite part;
- melting the portion within the receptacle and flowing the chopped fiber within the receptacle within the die;
- and
- compression molding the portion into the composite part.
A method of fabricating a portion of an aircraft, the method comprising:
- reducing a bulk factor of chips comprising chopped fiber while heating, to a temperature between six hundred and eight hundred degrees Fahrenheit, and forming the chips into a pre-consolidated charge;
- separating shaped volumetric charges from the pre-consolidated charge;
- placing a shaped volumetric charge of the shaped volumetric charges into a receptacle within a die, wherein the shaped volumetric charge has a mass equal to the portion of the aircraft;
- melting the shaped volumetric charge within the receptacle and flowing the chopped fiber within the receptacle within the die;
- and
- compression molding the shaped volumetric charge into the portion of the aircraft.
A non-transitory computer readable medium embodying programmed instructions controlling, when executed by a processor, a method for fabricating a composite part, the method comprising:
- reducing a bulk factor of chips comprising chopped fiber while heating, to a temperature between six hundred and eight hundred degrees Fahrenheit, and forming the chips into a pre-consolidated charge;
- separating portions from the pre-consolidated charge;
- placing a portion of the portions into a receptacle within a die, wherein the portion has a mass equal to the composite part;
- melting the portion within the receptacle and flowing the chopped fiber within the receptacle within the die;
- and
- compression molding the portion into the composite part.
