Composite Wing

3D printing has allowed complex designs to be produced that were impossible to create using conventional manufacturing processes. Aircraft wings are optimized as much as possible given manufacturability considerations, but more complex geometry could provide the same strength for less weight, increasing aircraft performance. Although carbon fiber composites are some of the best known materials for conventional optimized aircraft wings, current 3D printing technology cannot produce this material. Instead, it is currently limited to metals and polymers. To determine if the more complex geometry which can be produced by 3D printing can offset the material limitations, a carbon fiber composite wing and a redesigned, 3D printed 7075-T6 aluminum wing were compared using Finite Element Analysis. The unoptimized 3D printed aluminum wing had a superior safety factor against fracture/yielding (1,109% higher) and buckling resistance (127.3% higher), but at the cost of a 23.99% mass increase compared to the optimized carbon fiber composite wing. If the 3D printed aluminum wing had been optimized to provide the same safety factor against fracture/yielding and buckling resistance as the carbon fiber composite wing, it is anticipated that the resulting design would be significantly lighter, thus increasing aircraft performance.

Carbon fibers are excellent materials for engineering biomedical materials and devices owing to their functional properties of low weight, high strength, high chemical and thermal stability, and blood and cell compatibility. Recent studies have demonstrated that the carbon fibers could be used as a scaffolding system for bone repair and regenerative application. However, carbon fiber-based composite products lack the long-term retention of their biological property upon implantation, which greatly affects their wider biomedical applications. In this study, design and fabrication of carbon fibers composite scaffolds using a fast 3D printing technology has been successfully realized, which provides a new direction for the biomedical application of carbon fiber composite materials.

3D Printing Technique

The properties of composite materials do not depend only on the properties of raw materials but also other parameters such as volume fraction, geometry, dimension and material distribution etc. Carbon fiber reinforced polymer is one of the top choices of composite material because carbon fiber has light weigh with high tensile strength. For fiber-based composite such as carbon fiber composite, directions of carbon fiber with respect to loading direction could also affect to the strength of composite material under load. In this work, the properties of short carbon fiber-resin composite were investigated (fiber length of 0.2 mm.) with two different fiber orientations, i.e. 0 and 90 degrees to applied load. The 3D printing technique was employed in order to control carbon fiber direction and minimize material loss leading to material cost reduction. It was found that 3D printing technique could control direction of fiber in most case. However, at area with high curvature, the unexpected fiber direction was observed due to post hot process during which material flow was expected. It should also be noted that fiber path during 3D printing process may be very crucial as it could result in low strength local area due to low fiber density. This area could promote stress concentration leading to final fracture.

This study investigates the possibility analysis of UAV propeller made by commercial 3D printing machine. The primary experimental facility is 3D printer based on Fused Deposition Modeling method (FDM). The main methodology of this work is to construct standard test piece according to ASTM standard and use for standard test. The Polylactic Acid (PLA) and carbon fiber composite material are the main two printing materials in this work. Experimental results reveal that the strength and bending of these two materials are enough to be the propeller of middle size UAV, especially the carbon fiber composite material. This study not only confirms the application possibility of UAV propeller made by 3D printing, but also carries out the real flight test to identify performance enhancement and future application.

Aiming at the limited mechanical properties of general thermoplastic 3D printed models, a 3D printing process method for selective enhancement of continuous carbon fiber composite material is proposed. Firstly, the selective enhanced double nozzle working mechanism and crafts planning process are put forward. Then, based on the double nozzle carbon fiber 3D printing device, test samples are printed by polylactic acid (PLA) and carbon fiber material, and the test samples are enhanced by inserting layers of continuous carbon fiber material. The performance test of the samples is carried out. Experiment results show that when the volume fraction of continuous carbon fiber material increases gradually from 5% to 40%, the tensile strength increases from 51.22 MPa to 143.11 MPa. The performance improvement curve is fitted through experimental data. Finally, field scanning electron microscopy is used to observe the microscopic distribution of continuous fibers in the samples. The results of the research lay the foundation for the performance planning of 3D printed models.
