A compactor is disclosed for use with an additive manufacturing print head. The compactor may include a housing connectable to the additive manufacturing print head. The compactor may also include a compacting wheel, and at least one spring disposed in the housing and configured to exert an axial force on the compacting wheel. The compactor may further include a piston moveable to adjust a distance between the housing and the compacting wheel.

Composite materials include a steel matrix with reinforcing carbon fiber formed of individual fibers penetrating into the matrix to substantial depth. The fibers typically have defined diameters and large ratios of penetration depth to fiber diameter. Specified methods for forming the composite materials have a unique ability to achieve the large ratios of penetration depth to fiber diameter.

Composite materials include a steel matrix with reinforcing carbon fiber integrated into the matrix, and having unreinforced regions suitable for stamping or other deformation. The composite materials have substantially lower density than steel, and are expected to have appreciable strength within regions having the reinforcing carbon fiber, while having greater deformability in unreinforced regions. Methods for forming composite steel composites includes combining at least two laterally spaced apart reinforcing carbon fiber components, such as a carbon fiber weave, with steel nanoparticles and sintering the steel nanoparticles in order to form a steel matrix with reinforcing carbon fiber integrated therein, and unreinforced regions located in the lateral spaces between carbon fiber components.
