Abstract
Methods and apparatus for additive manufactures of complex parts using co-aligned continuous fibers are disclosed. Filament subunits having complex shapes are fabricated and inserted into a mold cavity. The layup is compression molded to form a complex part having high tensile strength.
Claims20
An assembly layup of filament subunits for molding a fiber-reinforced composite part, the assembly layup comprising:
- a plurality of first filament subunits, each of the first filament subunits including a bundle of co-aligned fibers impregnated with a first matrix material, the first filament subunits being organized into an arrangement having a shape that is substantially similar to a first shape of the fiber-reinforced composite part, or to a second shape of a portion of the fiber-reinforced composite part;
- and
- at least one second filament subunit, the second filament subunit comprising non- aligned fiber impregnated with a second matrix material, wherein the second filament subunit is disposed at an intersection of two adjacent first filament subunits of the plurality thereof, and wherein the two adjacent first filament subunits form an exterior portion of the arrangement.
An assembly layup of filament subunits for molding a fiber-reinforced composite part, the assembly layup comprising:
- a plurality of first filament subunits, each of the first filament subunits including a bundle of co-aligned fibers impregnated with a first matrix material, the first filament subunits being organized into an arrangement having a shape that is substantially similar to a first shape of the fiber-reinforced composite part, or to a second shape of a portion of the fiber-reinforced composite part, wherein each of the first filament subunits is not in the form of a tape or a sheet of material;
- and
- at least one second filament subunit, the second filament subunit comprising non-aligned fiber impregnated with a second matrix material, wherein the second filament subunit is disposed at an intersection of two adjacent first filament subunits of the plurality thereof, and wherein the two adjacent first filament subunits form an exterior portion of the arrangement.
