Prediction of four Si3N4 compounds by first-principles calculations

open access: yesAIP Advances, 2023
Four Si3N4 crystal structures were predicted using an ab initio evolutionary methodology. The mechanical and dynamic stabilities were confirmed by the density functional theory assuming zero-pressure conditions. Energetic stability calculations indicated

Yarn on yarn abrasion performance of high modulus polyethylene fiber improved by graphene/polyurethane composites coating

open access: yesJournal of Engineered Fibers and Fabrics, 2021
As a high-performance fiber, high modulus polyethylene fiber (HMPE) has been widely used in the rope industry. However, due to its low melting point and poor thermal conductivity, it tends to break under the conditions of repeated yarn on yarn abrasion ...

Effect of Nanosilica on the Mechanical Properties, Compression Set, Morphology, Abrasion and Swelling Resistance of Sulphur Cured EPDM/SBR Composites

open access: yesSilicon, 2021
The main objective of the current research work is to explore the effect of nanosilica particles on the compound EPDM/SBR-SiO2 (ethylene-propylene-diene monomer/styrene-butadiene rubber-nanosilica). The composite EPDM/SBR with and without silane coupling

Yarn on yarn abrasion failure mechanism of ultrahigh molecular weight polyethylene fiber

open access: yes, 2021
Yarns of fiber assemblies such as ropes would abrade with each other during repeated stretching or bending. The yarn on yarn abrasion failure is a main reason for the final assembly failure as the result of the relative movement to each other. To explore
