“…Figure 4 shows the cross‐sectional topography of different specimens. It can be seen from the figure that CFP is successfully deposited on the surfaces and interlaminations of the specimens, and the deposition density of CFP has a significant effect on the morphology 25–27 . From Figure 4A1–D1, it can be seen that there are many pores between the original specimen layers, the textured pits woven by the carbon fiber bundle on the specimen surfaces have only a small amount of resin distribution, which is not enough to make the surface become completely flat.…”

Carbon fabric/resin laminated composites (CFRC) are extensively used in aerospace, transportation, and other fields owing to their superiorities of lightweight, high strength, and convenient integral molding. Therefore, strong interlaminar binding and prominent wear resistance are urgent requirements for avoiding premature failure of laminated materials in harsh working environments. To elevate the superficial wear resistance and interlaminar bonding strength of composites simultaneously, the modified composites were obtained by introducing carbon fiber powder (CFP) with different densities on the surface of the composites and between layers. The experimental results indicate that CFP can be evenly distributed in the interlaminar resin enrichment zone of the sample (CFRC‐40) when the deposition density is 40 g/m2. Consequently, CFRC‐40 presents optimal thermal conductivity owing to better heat transfer bridges between layers of the composite established by CFP. At the same time, the mechanical properties such as the tensile, impact, and interlaminar shear strengths of CFRC‐40 are improved by 42.8%, 10.2%, and 8.5%, respectively, compared with the original CFRC, which are attributed to the absorption of crack propagation energy and the inhibition of crack propagation by CFP. Furthermore, the dynamic friction coefficient maintains at a high level after introducing CFP with a density of 40 g/m2, while the wear rate significantly decreases by 61.2% from 12.99 × 10−14 m3(N m)−1 to 5.04 × 10−14 m3(N m)−1. This study proposes an innovative strategy to improve the interlaminar bonding of carbon fabric/resin laminated composite, which is conducive to obtaining composite with excellent mechanical and tribological properties.Highlights A facile and effectual method was adopted to introduce carbon fiber powder (CFP) into the interlamination and surface of the composites simultaneously. The mechanical properties and abrasive resistance of the composites were obviously strengthened by regulating the content and distribution of CFP. CFP at a certain scale, could not only hinder the propagation of cracks but also alleviate the surface wear and extend the service life of composites.

A Property‐Driven Stepwise Design Strategy for Multiple Low‐Melting Alloys via Machine Learning

Low-melting alloys (LMAs), composed of metal elements such as Sn, Pb, Bi, Cd, In, Ga, and Zn, have been widely used as fuse, transmission medium, and brazing filler metal in the electronics industry. [1][2][3] However, with the development of environmental protection and electronic technology, binary lead-containing LMAs are insufficient to meet the requirements of the electronics industry. [4,5] From a manufacturing point of view, the melting point may be the first and most important factor to consider. Nevertheless, the research on the melting point of LMAs mostly focuses on binary alloys. Chelikowsky and Anderson [6] found that the melting point of intermetallic binary alloys can be roughly estimated by averaging the melting points of the constituent elements. Pan et al. [7] derived the liquid line equations to calculate the melting point of binary LMAs, and then the equations were extended into multiple alloys. However, the errors of melting point presented an increasing extent with the increasing number of components, and the error of the quaternary alloy samples exceeded 20 C. That may be caused by the complex microstructure and sophisticated phase composition of LMAs. On the contrary, the lack of basic physical and chemical data brings great difficulties to the calculation of melting point for multiple LMAs. Therefore, it is not convenient for us to design multiple LMAs with a specific melting point by using "trial and error" method in tremendous chemical space.In recent years, fast-developing machine learning (ML) methods have been successfully utilized in alloy compositions design. [8][9][10][11][12][13][14] Wang et al. [15] proposed a property-oriented design strategy with the target of ultimate tensile strength and electrical conductivity based on the BP neural network to accelerate the discovery of high-performance copper alloys. Wen et al. [16] formulated a materials design strategy with experimental design algorithms, active learning, and a utility function to search for high entropy alloys with large hardness. Rickman et al. [17] proposed a supervised learning strategy that combines a multiple regression analysis or its generalization, a canonical-correlation analysis (CCA), and a genetic algorithm to efficiently screen the high-entropy alloys. And machine learning has yielded satisfactory performance in the prediction of melting points of different materials. For example, Bhat et al. [18] reported the melting point of organic molecules with a simple ensemble of extreme learning

Sintering temperature can significantly affect the mechanical behaviors of ceramic matrix composites. Herein, the effect of sintering temperature (900–1200 °C) on micro‐ and macromechanical properties of an oxide fiber‐reinforced oxide matrix (oxide/oxide) composite is investigated. The crack propagation path is predicted by the He–Hutchinson model. Results show that the elastic modulus of matrix and interfacial shear strength increase with sintering temperature. The propagating crack converts from deflection along the interface to direct penetration into the matrix at 1200 °C. With increase of the sintering temperature, the flexural strength and interlaminar shear strength monotonically increase, while the fracture toughness increases and then decreases at 1200 °C. A good balance between the fracture strength and fracture toughness is achieved on the 1100 °C sintered composite, which possesses a high flexural strength of ≈276.7 MPa, a high interlaminar shear strength of ≈17.2 MPa, and a high fracture toughness of ≈13.9 MPa m1/2. The study offers a new sight in deep understand of the preparation and applicability of oxide/oxide composite at high temperatures.
