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.

There is disclosed an apparatus for winding filaments to form a structure. The apparatus includes a carrier which mounts spools of fiber, a mandrel, and a guide element which directs fiber tows, comprising filaments from the spools, onto the mandrel. The system further includes a heating element which applies heat to the fiber tows, and a diaphragm element which defines an orifice about the mandrel. The diaphragm element includes one or more displaceable portions which define a physical dimension of the orifice and which: displace to vary the physical dimension of the orifice; and apply a predetermined pressure to the fiber tows disposed on the mandrel. Also disclosed and described is a related method.

System for in-situ consolidation and curing of composite structures

Systems and methods for rapid mold tooling fabrication using active self-shaping non-Newtonian fluids is provided. The rapid mold fabrication system includes one or more molding units between which molds are formed using compression or injection molding process. Each molding unit includes an array of hydraulic pillars that controllably adjust the position of mold preform layers, and an expandable fluid chamber between the end of the pillars and the preform layer against which a mold is formed. A control system is also provided for controlling the volume of STF within the chamber and for transitioning the STF from a liquid to a solid phase through application of an electrical stimulus. A method is also provided for manufacturing a mold using the system. A method is also provided for measuring the geometric properties of objects using the rapid mold fabrication system.

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.

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.
