Abstract: A system for the functionalization of polyolefin fiber includes a reactor chamber, a fiber pulley system, and a precursor sprinkler system. The reactor chamber defines an interior reactor space and a plurality of fiber inlet/outlet pairs positioned at opposite ends of respective fiber processing axes. The fiber pulley system is arranged to direct polyolefin fiber through the plurality of fiber inlet/outlet pairs, along a fiber processing path comprising the respective fiber processing axes. The precursor sprinkler system is operable to aerosolize a precursor solution and contact the aerosolized precursor solution with the polyolefin fiber. A method for functionalizing polyolefin fiber includes aerosolizing the precursor solution to form an aerosolized precursor solution, passing polyolefin fiber along the fiber pulley system into the reactor chamber, contacting the polyolefin fiber with the aerosolized precursor solution, and passing functionalized polyolefin fiber out of the interior reactor space of the reactor chamber.

Abstract: A system is disclosed for three-dimensional (3D) printing of multi-directional woven components with hierarchical z-axis reinforcements using pre-impregnated FRP materials. The exemplary 3D printing system includes a primary extrusion nozzle system and a secondary extrusion needle system supported by a multi-axis truss. The primary extrusion nozzle system is comprised of at least two sub-extruders and rotation mechanisms for controllably rotating the extrusion nozzle and rotating the two-sub extruders. The extrusion nozzle assembly and the two sub-extruders can be controllably and independently rotated to extrude a braided yarn with a precise fiber-spacing. Additionally, a separate extrusion needle is provided for vertical interpenetration of the needle into the braided workpiece such that material can be extruded at precise depth through side-facing needle openings thereby providing z-axis reinforcement to the workpiece.

Abstract: Systems and methods for determining a damage value of one or more composite components and/or a vehicle using digital image correlation are disclosed. Digital image correlation is used to evaluate a displacement of one or more nanoparticles that are deposited on and/or embedded within the composite component. Digital image correlation is performed by identifying a first reference entry indicating a reference position of the one or more nanoparticles and correlating the first reference entry with sensor data of the composite component indicating a position of the one or more nanoparticles. The damage value of the composite component is determined based on the digital image correlation between the sensor data and the first reference entry.
