Fused deposition modeling of carbon‐reinforced polymer matrix composites: A comprehensive review

Polymer Composites (2023)

Qinghua Wei Rongbin Yang Xudong Zhao Jiayi Zhou Yalong An

Abstract Carbon‐reinforced polymer matrix composites (PMCs) have been thoroughly applied in different fields because of their benefits, such as low specific gravity, corrosion resistance, good electrical conductivity, and robust mechanical properties. Especially, with the emergence of fused deposition modeling (FDM) technology has further promoted the application of such materials in complex structural components. Recently, FDM printing carbon‐reinforced PMCs have become a hot topic in composites research, and many promising results have been achieved around related research. In order to help readers have a comprehensive and systematic understanding of the latest research progress of FDM printing carbon‐reinforced PMCs in terms of material modification, processing, material properties, and application levels, this paper reviews the properties and processes of FDM printed carbon‐reinforced PMCs and their potential applications in aerospace, flexible sensing, electrochemistry, and biomedical fields. The effects of commonly used carbon reinforcing materials on the performance of FDM printed PMCs were contrasted and analyzed. Moreover, the process optimization of printing carbon‐reinforced PMCs was introduced and highlighted. Finally, the current challenges and future research directions of FDM printing carbon‐reinforced PMCs were analyzed and prospected.

Digital micro-mirror device-based detector for particle-sizing instruments via Fraunhofer diffraction

Applied Optics (2015)

Jiayi Zhou Zhang Cao Heng Xie Lijun Xu

In this paper, a digital micro-mirror device (DMD)-based detector is proposed for the detection of light intensity in particle-sizing instruments using Fraunhofer diffraction. The detector consists of only one photodiode, which eliminates the distortions caused by the nonuniformity of the detector arrays used in traditional instruments. The center of the diffraction pattern was accurately located to distribute the optimized arc-shaped mirror arrays for the intensity detection. Both simulated and experimental results showed that the proposed detector was superior to the classical one as it was less sensitive to noise than the detector arrays used in traditional systems.

Novel Mechano-Luminescent Sensors Based on Piezoelectric/Electroluminescent Composites

Sensors (2011)

Yanmin Jia Xiangling Tian Zheng Wu Xiaojuan Tian Jiayi Zhou

A high-sensitivity mechano-luminescent sensor was fabricated on the basis of piezoelectric/electroluminescent composites. The working principle of this mechano-luminescent sensor was elucidated by analyzing the relationship between the piezoelectric-induced charges and the electroluminescent effects. When a stress is applied on the piezoelectric layer, electrical charges will be induced at both the top and bottom sides of the piezoelectric layer. The induced electrical charges will lead to a light output from the electroluminescent layer, thus producing a mechano-luminescence effect. By increasing the vibration strength or frequency applied, the mechano-luminescence output can be obviously enhanced. Mechano-luminescence sensors have potential in smart stress-to-light devices, such as foot-stress-distribution-diagnosis systems and dynamic-load-monitors for bridge hanging cables.

Coupled effect of Ag and In addition on the microstructure and mechanical properties of Sn–Bi lead-free solder alloy

Journal of Materials Research and Technology (2023)

Tianhan Hu Shun Li Zhen Li Guanzhi Wu Ping Zhu

The microstructure and mechanical properties of Sn-Bi solder alloys with various Ag and In addition are comparatively investigated. The results illustrate that the tensile strength and ductility of the solder alloy could be dramatically enhanced with negligible loss of the plasticity. Especially, the Sn-Bi solder alloy with 0.4 wt. % Ag and 1.5 wt. % In exhibits the maximum tensile strength and elongation of 79.7 MPa and 45.9%, respectively. The microstructure of the Sn-Bi solder alloys is mainly composed of Bi-rich and β-Sn phases. With the addition of elements Ag and In, the microstructure is significantly refined, and the lamellar eutectic structure with thinner interlayer spacing could be detected. Element Ag tends to form Ag3Sn phase while element In solutes in the Sn matrix. The mechanical properties of the as-prepared Sn-Bi solder alloy are improved attributed to the precipitated-phase strengthening of the fined Ag3Sn phase and the refinement effect of In on coarse Bi-rich phase.

Liquid Metal Embrittlement Susceptibility and Crack Formation of the Zn-Coated Complex Phase Steel

Materials (2024)

Rongxun Hu Jiayi Zhou Yu Sun Lei Ming Yulai Gao

In the resistance spot-welding (RSW) of galvanized complex phase (CP) steel, liquid metal embrittlement (LME) may occur, deteriorating the welded joint’s performance. Based on the Auto/Steel Partnership (A/SP) standard, the joints of galvanized CP steel welded with a welding current from 7.0 kA to 14.5 kA were evaluated. When the welding current increased to 11.0 kA, LME cracks began to appear. The longest type A crack was 336.1 μm, yet the longest type D crack was 108.5 μm, and did not exceed 10% of the plate thickness, which met the limitation of the A/SP standard. In light of the microstructural observation and element distribution, it was found that there existed an internal oxide layer adjacent to the surface of galvanized CP steel matrix, with the depth of about 4.1 μm. In addition, the simulation results show that the CP steel was under tensile stress throughout the RSW process, but the internal oxide layer could successfully lead to the low LME susceptibility of the Zn-coated CP steel.

超音波ロボット初期位置決めのための呼吸変動計測による肋骨検出

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) (2023)

Kodai OKUZAKI Norihiro Koizumi Yu Nishiyama Jiayi Zhou Tomohiro ISHIKAWA

Scanning path planning is an essential technology for fully automated ultrasound (US) robotics. During abdominal US scanning, the ribs are critical body surface landmarks for scanning path planning. We proposed a method for determining the rib region using RGB-D images and respiratory variation. We generated a depth difference image by finding the difference between the depth image taken at the resting inspiratory position and the depth image taken at the maximum inspiratory position, which clearly shows the rib position. The rib position was then determined by yolov5 object detection model to this depth difference image. In the experiment conducted with nine subjects, the proposed method of rib detection using depth difference images marked an IoU of 0.951 and average confidence of 0.77. The average error between the ground truth and predicted positions was 15 pixels ≃ 7.5 mm. The results were superior to rib detection using only the RGB image.
