Abstract Fabric composites are widely employed in self-lubricating bearing liners as solid lubrication materials. Although the tribological behaviors of fabric have been extensively studied, cryogenic properties and mechanisms scarcely reported largely unclear to instruct material design for aerospace other high-tech applications. Herein, polytetrafluoroethylene (PTFE)-based hybrid-fabric were investigated at ambient temperatures form pin-on-disk friction under heavy loads. The results...
Abstract High-performance polymer friction materials with tunable tribological behavior to fit varied work conditions remain a challenge of widespread interest for variety applications. Shape memory exhibits morphing and modulus changing over temperature provides promising material adjust the process. Herein, we investigated properties shape cyanate ester (SMCE) under different conditions. The SMCE good stable high coefficient (COF) low wear rate. Besides, COF increases rate decreases...
Utilization of ultralow sulfur diesel (ULSD) having intrinsically low lubricity has been mandated in more and countries for meeting increasingly stringent emission regulations. Our work demonstrated that epoxy hybrid nanocomposites, reinforced with carbon fibers Al2O3 or AlN nanoparticles, offered extraordinarily friction wear when lubricated ULSD. More interestingly, sliding took place under lubricant starvation conditions, almost no thanks to the formation a nanostructured tribofilm. We...
The development of smart lubricating materials with lasting lubrication and outstanding wear resistance while achieving speed response is great significance in the field bearing cage applications but has proven to be challenging. Herein, polyimide (PI) molding powder containing two kinds PI different rigidities synthesized situ fabricate a two‐scale porous (PPI) by (cold hot) isostatic pressing. unique structure originates from bimodal particle size distribution powder. oil stored PPI...
High-temperature-resistant and self-lubricating polymer composites with long life high reliability are increasingly indispensable in the aerospace field. Herein, ZIF-67 grown on MXene lamella was successfully prepared, ZIF-67@MXene/PI a regular layered structure were obtained by hot-pressing three-dimensional network aerogel. It revealed that incorporating ZIF-67@MXene into PI dramatically reduced friction abrasion elevated temperatures. Largely, aerogel walls always paralleled sliding...
In this work, a novel three-dimensional (3D) composite (GBS) based on melamine foam is fabricated by layer-by-layer self-assembly of positively charged hexagonal boron nitride ( h -BN) and negatively graphene oxide (GO) nanosheets. Improved tribological thermal management performance are achieved combing GBS with two different polymers (thermosetting epoxy phase-reversible paraffin wax). First, the 3D-structure not only solves problem dispersion additives in but also significantly reduces...
