Quantitative relations between curing processes and local properties within thick composites based on simulation and machine learning

open access: yesMaterials & Design, 2023
Overheating is almost inevitable during the curing of thick polymer matrix composite parts, which always induces degradation of the mechanical properties.

Influence of Composite Thickness on Ultrasonic Guided Wave Propagation for Damage Detection

open access: yesSensors, 2022
In this paper, the propagation properties of ultrasonic guided waves (UGWs) in different-thickness composites (i.e., 2, 4 and 9 mm) were critically assessed, and their effectiveness for damage detections and localisations under varying temperatures was ...

The accumulation and growth of Pseudomonas aeruginosa on surfaces is modulated by surface mechanics via cyclic-di-GMP signaling

open access: yesnpj Biofilms and Microbiomes, 2023
Attachment of bacteria onto a surface, consequent signaling, and accumulation and growth of the surface-bound bacterial population are key initial steps in the formation of pathogenic biofilms.

Effects of pyrocarbon interphase on microstructure and properties of C/SiBCN composites

open access: yesMaterials Research Express, 2023
C/SiBCN composites are expected to be widely used in aerospace applications because of their excellent high-temperature stability. However, the interfacial reactions have significantly limited their practical application.
