Abstract: A composite panel comprises a first skin and a second skin. A core is arranged between and attached to the first skin and the second skin. The core includes Z zones that are 3D printed using a thermoplastic material. Each of the Z zones abuts and is connected to another one of the Z zones. Each of the Z zones has one of D densities and at least one of the Z zones had a different density that another one of the Z zones. Z and D are integers greater than one.

Abstract: A reconditioning device includes: a first shearing plate; a second shearing plate; and a housing. The housing includes: a first member configured to hold the first shearing plate and comprising an input for receiving a material; a second member connected to the first member to form an inner cavity, a portion of the inner cavity is located in a gap between the first shearing plate and the second shearing plate; and an output member connected to a pipeline of a production applicator and configured to output the material subsequent to shearing. The shaft extends through the second member, is connected to the second shearing plate, and is configured to be rotated to shear the material disposed in the gap between the first shearing plate and the second shearing plate.

Abstract: An energy-absorbing assembly for a vehicle includes a carrier plate and a plurality of discrete energy-absorbing elements. The carrier plate includes a first polymer and a first plurality of reinforcing fibers. The plurality of energy-absorbing elements each includes a second polymer and a second plurality of reinforcing fibers. The plurality of energy-absorbing elements is fixed to the carrier plate. Each energy-absorbing element of the first plurality of energy-absorbing elements includes an elongated hollow structure defining a longitudinal axis extending nonparallel to the carrier plate. Another energy-absorbing assembly includes a carrier plate and a plurality of discrete energy-absorbing elements. The carrier plate includes a first polymer and a first plurality of reinforcing fibers. The plurality of energy-absorbing elements each includes a second polymer and a second plurality of reinforcing fibers. Each energy-absorbing element includes a transverse wall and is fixed to the carrier plate.
