High fracture strength and toughness are vital requirements for the Al2O3/Al2O3 composites. This advanced structural material is composed of two-dimensional alumina fiber fabrics with porous matrices. However, composites exhibit low delamination resistance under shear stress. In this study, an as-fabricated composite was densified through a slurry infiltration sintering (SIS) process. The SIS-cycle-dependent mechanical properties were investigated. results showed that matrix strengthened,...
An aerial Radio Environment Map (REM) characterizes the spatial distribution of Received Signal Strength (RSS) across a geographic space interest, which is crucial for optimizing wireless communication in air. Aerial REM construction can rely on Unmanned Vehicles (UAVs) to autonomously select interesting positions sampling RSS data, enhancing quality construction. However, due lack prior information about environment, it challenging UAVs determine suitable online. Additionally, achieving...
In the field of maritime safety research, ship behavior analysis is usually based on data provided by automatic identification systems (AISs). Prevailing studies predominantly focus detecting behaviors vessels that may affect safety, especially abnormal disappearance AIS signals, neglecting subsequent measures to trace these illegal ships. To fill this gap, we propose a deep learning model named multi-dimensional convolutional long short-term memory (MConLSTM) tackle challenge recognizing...
Sintering temperature can significantly affect the mechanical behaviors of ceramic matrix composites. Herein, effect sintering (900–1200 °C) on micro‐ and macromechanical properties an oxide fiber‐reinforced (oxide/oxide) composite is investigated. The crack propagation path predicted by He–Hutchinson model. Results show that elastic modulus interfacial shear strength increase with temperature. propagating converts from deflection along interface to direct penetration into at 1200 °C. With...
Herein, a three‐dimensional (3D) oxide fiber reinforced matrix (oxide/oxide) composite is fabricated via slurry infiltration and sintering process. Subsequently, the effects of thermal aging on microstructure mechanical properties 3D oxide/oxide at 900 1100 °C are investigated. Experimental results indicate that affects microstructures fiber/matrix interface. The elastic modulus interfacial shear strength increases with temperature time. Aging treatment for 100 300 h in moderate decrease...
Abstract A novel methodology combining multiscale mechanical testing and finite element modeling is proposed to quantify the sintering temperature‐dependent properties of oxide matrix composites, like aluminosilicate (AS) fiber reinforced Al 2 O 3 (AS f /Al ) composite in this work. The results showed a high‐temperature sensitivity modulus/strength AS due their phase transitions at 1200°C, as revealed by instrumented nanoindentation technique. interfacial strength, measured push‐in...
A novel Si3N4 fiber reinforced SiC matrix composite has been prepared and the micro-mechanical properties of composites in situ have explored. For fibers, remained almost unchanged with increasing fabrication temperatures. In comparison, for PCS derived matrix, higher temperature could trigger more β-SiC formations, which led to enlarging corresponding properties. The microstructure analysis interfacial zones revealed strong reactions existing fabricated at ≥800 °C. Therefore, shear strength...
