Summary: In this investigation, different weaving patterns of Kevlar and pineapple leaf fiber (PALF) reinforced epoxy composites were fabricated, and their solid particle erosion wear properties, water absorption, and thickness swelling behavior were tested. The results showed that basket weave type and pure Kevlar fiber reinforced epoxy composites had better water absorption and thickness swelling properties. Twill type and pure Kevlar fiber reinforced epoxy composites showed superior erosion wear resistance. Taguchi analysis indicated that twill type Kevlar/PALF reinforced epoxy composites had the minimum erosion wear rate under specific conditions.

Summary: Carbon fibre reinforced polymer composites have superior properties and are increasingly used in industries like aerospace. Structural health monitoring is necessary due to their complex failure mechanisms. Magnetostrictive materials have been effective in damage detection but need improvement in spatial sensitivity. It is important to demonstrate ease of fabrication, damage detectability, and maintain a good weight-to-cost trade-off.

Summary: This investigation develops and characterizes a type of multi-phase hybrid composites made of bi-directional ramie fibers, epoxy resin, and micro-sized titania particles in different proportions. The composites are fabricated using the hand layup technique and subjected to physical, compositional, and mechanical characterization tests. The results show that the inclusion of titania particles improves the mechanical properties and hardness of the composites, making them potentially useful as functional materials in wear-prone situations.

Summary: This study examined the erosion of rubber particle-reinforced epoxy composites by angular silicon carbide particles, finding that the erosion rates were significantly lower than neat epoxy. By incorporating a new mixture rule based on reinforcement areal coverage, the erosion rates could be predicted within a small margin of error. The methodology developed in this study may be useful in predicting the erosion rate of other composites with elastomeric reinforcements.

Summary: The study investigated the influence of graphene nanoplatelets (GNPs) and carbon foam (CF) micrograins on the morphology and thermomechanical and tribological properties of epoxy composites. Binary composites containing either CF grains or GNPs and multiphase composites with CF particles and GNPs together were prepared using two different procedures. CF, when combined with GNPs, significantly improved the storage modulus, hardness, thermal stability, and reduced the friction coefficient and wear rate compared to the epoxy matrix. Among the two methods, the composite fabricated by the first method demonstrated superior tribological properties, especially under higher wear loads.

Summary: This study aims to understand granule formation in a fluidized bed by analyzing particle class evolution, Raman spectra, and microscopy. The experimental conditions were divided into wet and dry based on different operating parameters. The results show that wet conditions with a higher amount of liquid binder on the particle surface favor the formation of a sticky layer, leading to more effective particle formation.

Summary: This study fabricated Ti-10 wt% Mo-1 wt% B4C composites using the SPS technique and investigated the effects of sintering temperature and dwell time on their microstructure and mechanical properties. A high relative density of 99.92% was achieved for the composites sintered at 1450 degrees C and further hot-rolled at 900 degrees C. X-ray analysis illustrated the formation of in-situ phases during the SPS process, while microstructural investigation confirmed the influence of sintering temperature and holding time on reducing porosity. Additionally, the post hot rolling at 900 degrees C was shown to modify the microstructure and activate the strengthening mechanism in the prepared composites.

Summary: This study describes a method for preparing dense, micro, and nanoporous aramid films containing hexagonal boron nitride (hBN) to improve mechanical performance and thermal conductivity. Results showed that adding 10% hBN to microporous aramids increased Young's modulus by 130% and reduced density by 63%. The films containing hBN also exhibited enhanced thermal conductivity and diffusivity, making them suitable for applications in aerospace industry, protective equipment, and battery separators.

Summary: The TiZrNb metal-matrix composites reinforced by in-situ formed borides were produced using different amounts of TiB2. The composites exhibited varying microstructures and mechanical properties with the increase in boride content. Load transfer strengthening was found to be the main contributor to the overall strength of the composite. The biocompatibility evaluation suggested a decrease in the proliferation rate of mesenchymal stem cells with an increase in boride content.

Summary: The novelty of this study lies in constructing an Entropy-based wear and fluid-solid-thermal (FST) coupled model for journal bearings, and revealing the transient interaction behavior between wear evolution and FST evolution during repeated starting and stopping. The wear rate is measured experimentally, and the contact temperature, friction coefficient and normal contact force are obtained from the validated FST model. Wear tests and numerical calculations are conducted to validate the predicted wear rate and investigate the time-varying wear and FST evolution of journal bearings.

Summary: A polymer coating prepared by liquid spraying technology on the surface of 20CrMo steel demonstrates good tribological and anti-cavitation erosive properties. It can effectively replace CuPb24Sn copper alloy in valve plates for pumps under different lubrication conditions. The coating exhibits adhesive wear and reduces frictional loss, and mainly shows abrasive wear under complex working conditions. Its lipophilicity, high hardness to elastic modulus ratio, and corrosion resistance are the main influencing factors for its performance.

Summary: This study explores the relationship between the wear rate of train brake pads and its features, and proposes a method for predicting the wear rate suitable for small sample data. Grey relational analysis and Pearson correlation analysis are used to determine the preferred features that affect the wear rate, and a BOA-BP model is established for prediction. The results show that BOA-BP exhibits better advantages in prediction with small samples.

Summary: This study simulated the rolling contact of a driving wheelset over tangent and curved tracks at a speed up to 500 km/h using an explicit finite element approach to derive creep curves. The comparison between quasi-steady curves and transient curves in the presence of rail corrugation helped to identify cases where traditional theories are inapplicable and where transient effects must be considered. Additionally, the study further analyzed the influence of middle/high-frequency vibrations in the presence of rail corrugation.

Summary: The influence of high-carbon addition on the microstructure, hardness, and wear behavior of CoCrNi alloy was investigated. It was found that the addition of carbon resulted in the formation of carbide particles, enhancing the hardness and improving the wear resistance. Fracture and detachment of hard carbides during friction introduced additional abrasive particles, transitioning the wear mechanism from adhesive-dominated to abrasive-dominated.

Summary: This study reports the tribological behavior of nanodiamond plate (NDPL) as a nanoadditive for the first time and compares it with nanodiamond particles (NDPA). The results show that NDPL provides better lubrication performance at higher concentrations, and the sliding between NDPLs and the structural transformation from sp3 to sp2 carbon play a crucial role in lubrication and wear resistance.
