Devices, systems, and methods for generating a single fiber path of a composite material

A system comprising:

• one or more processors;
• and
• one or more nontransitory computer-readable mediums storing machine-readable instructions that, when executed, cause the one or more processors to:
• determine at least one of a height field and an orientation field of a fiber-reinforced structure, wherein the fiber-reinforced structure comprises a plurality of fiber portions and a polymer matrix;
• generate a reaction-diffusion representation of the fiber-reinforced structure, wherein the reaction-diffusion representation includes a hatching pattern or a heat map that indicates a concentration of at least one of the polymer matrix and the plurality of fiber portions;
• generate a two-phase representation of the fiber-reinforced structure based on the hatching pattern or heat map;
• designate a reference fiber deposition path based on the reaction-diffusion representation;
• generate a continuous fiber deposition path based on the reference fiber deposition path;
• and
• transmit a signal representing the continuous fiber deposition path to a deposition device, the deposition device using the continuous fiber deposition path to deposit a fiber of the fiber-reinforced structure;
• wherein the continuous fiber deposition path is generated by identifying and tracing a perimeter of the two-phase representation of the fiber-reinforced structure.
