Combination of continuous carbon fiber composites and 3D printing

ABS, PLA, nylon, resin, peek, and other 3D printing materials have become commonplace, as have other materials such as metals. A material's performance is improved by the addition of carbon fiber/glass fiber composites.

A critical factor limiting 3d printing technology's application is that the interlayer bonding force of the FDM process in the z-direction is significantly lower than the force in the X and Y directions. This is one of the major factors limiting its application. The bending spline printed in the vertical direction has excellent mechanical properties due to the incorporation of carbon fiber into the printed wire. The bending strength of the bending spline is 146 MPa due to the incorporation of carbon fiber into the printed were especially noteworthy is the fact that the bending strength is comparable to that of conventional injection molding parts.

Many benefits are provided by carbon fiber composites, including the ability to be used in the production of intelligent products and the ability to design with virtually no limitations.  The production of large quantities of materials on a commercial scale, however, is complicated by high labor costs and manufacturing speed constraints. The production of large parts is made easier by the use of these techniques. As a result of adjusting the printing direction and parameters, it can be observed that the 3D printer not only has excellent mechanical properties, but it also has a relatively smooth surface, which is an important feature in 3D printing. Herein lies the pivotal moment in the development and use of carbon fiber / glass fiber composites.

In traditional manufacturing, the combination of 3D printing and carbon fiber composites can improve the application of carbon fiber composites. A 3D printer that can print continuous fiber composites has been developed by a scientific research team at Xi'an Jiaotong University. As a result of combining FDM technology with continuous carbon fiber material, the mechanical and physical properties of printed parts become even better, and the design is low in cost and high in efficiency, while also being lightweight and customizable. The basic principle is that continuous fiber and thermoplastic filament are used as raw materials, and they are both fed into the same 3D print head at once. As soon as the plastic filament inside the print head is heated and melted, the fiber bundle is impregnated into composite material, which is then extruded and deposited on the printing platform through the nozzle outlet. When the composite matrix has been quickly cooled and adhered to the printing platform in the air, tension is created between the fixed fiber bundles and the fibers in the molten plastic wires that are subsequently extruded, allowing the continuous fibers to be continuously drawn out of the nozzle. The 3D printing head then extrudes the composite material from line to surface and from surface to volume under the control of the printing plate, resulting in the formation of 3D objects. The integration of composite material preparation and forming is accomplished through the use of this technological advancement.
