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

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

A Nonlinear Method for Characterizing Discrete Defects in Thick Multilayer Composites

open access: yesApplied Sciences (Switzerland), 2019
Discrete defects in thick composites are difficult to detect for the small size and the structure noise that appears in multilayer composites. In this paper, a nonlinear method, called recurrence analysis, has been used for characterizing discrete ...

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 ...

Influence of Composite Thickness on Ultrasonic Guided Wave Propagation for Damage Detection Using Embedded PZT Transducers

open access: yesApplied Sciences, 2023
This paper describes a study that focuses on assessing the influence of composites with different thicknesses (2 mm, 4 mm, and 9 mm) on embedded ultrasonic guided waves (UGWs) under varying temperatures.

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.

Performance of plaster composites incorporating rubber tire particles

open access: yesRevista Ingeniería de Construcción, 2020
Gypsum is the oldest synthetic construction material that is known, however it is a material about which there is little knowledge at the level of research, and in this work its study took place by making composites with the incorporation of rubber ...

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.

Variations in the Thickness and Composition of the Skin of the Giraffe [PDF]

open access: yesThe Anatomical Record, 2010
AbstractThis study examined the skin of two 1‐ to 2‐year‐old male giraffes and one adult male, determining skin thickness and histological structure with reference to it functioning as a component of the features required for the maintenance of blood pressure, dermal armor, or thermoregulation.

Mechanical Properties Evaluation for Cotton/Glass/Epoxy Hybrid Composite

open access: yesASM Science Journal, 2022
Natural fibre reinforced composites of any group are essential to satisfy the current demand and to keep the environment-friendly approach. In the present work, an attempt has been made to replace glass fibres partially by cotton fabric so as to reduce ...
