A print head is disclosed for use with an additive manufacturing system. The print head may include a matrix reservoir configured to hold a supply of matrix, and a flop guide located within the matrix reservoir. The flop guide may be configured to at least partially surround a continuous reinforcement passing through the matrix reservoir. The print head may also include a nozzle connected to an end of the matrix reservoir downstream of the flop guide.

A process for making a composite product comprises the steps of: A. Circumferentially plating a carbon fiber core with an alloy film including a film of high entropy alloy and liquid metal alloy or a film of metallic glass to form a film-clad carbon fiber thread; B. Weaving a plurality of said film-clad carbon fiber threads to form an interlaced film-clad carbon fiber sheet; and C. Vibrationally thermally pressing a plurality of said interlaced film-clad carbon fiber sheets as superimposed with one another to form a composite product.

A system is disclosed for additively manufacturing a composite structure. The system may include a print head configured to discharge a continuous reinforcement that is at least partially coated in a matrix, and a compactor configured to compact the continuous reinforcement and the matrix. The system may also include a cure enhancer configured to direct a path of cure energy toward the matrix after discharge, wherein the path of cure energy passes through at least a portion of the compactor.

A composite material is provided having functionalized carbon nanotubes and a metal matrix. It is obtained by a process including dispersing functionalized carbon nanotubes or a mixture of functionalized carbon nanotubes and of at least one metal, in an open-pore or semi-open-pore metal foam, in order to form a composite structure, and compacting the composite structure obtained in the preceding stage in order to form the composite material in the form of a solid mass.
