Non-destructive assessment of strain and mechanical fatigue in neat and glass fibre-reinforced epoxy via NIR spectroscopy

open access: yesPolymer Testing
In this study, changes in the near-infrared (NIR) spectrum in neat epoxy and glass fibre-reinforced plastic under tensile stress and cyclic fatigue loading are investigated. Specimens were fabricated using resin transfer moulding.

Behaviour of Hybrid Steel and FRP-Reinforced Concrete—ECC Composite Columns under Reversed Cyclic Loading

open access: yesSensors, 2018
Fibre-reinforced polymer (FRP) is used widely in concrete structures owing to its noncorrosive, light-weight, nonmagnetic, and high tensile-strength properties.

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Approach for safety assessment of glass fibre‐sizing agents in glass fibre‐reinforced plastics for food contact

open access: yesEFSA Journal, 2015
Following a request from the European Commission, EFSA was asked to review Commission proposals for classification of the substances used as sizing agents and provide an opinion on whether or not the proposed classifications could imply an unacceptable ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Carbon fibre recycling from milling dust for the application in short fibre reinforced thermoplastics [PDF]

open access: yes, 2017
A new approach to reuse accruing chips and dust from milling operations of carbon reinforced plastics (CFRP) is studied, show-ing how CFRP milling dust, in comparison to primary and pyrolysed fibres, can find application as a filler material in thermo ...

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Cigarette filter material and polypropylene fibres in concrete to control drying shrinkage [PDF]

open access: yes, 2012
Due to a reduction in demand for cigarette filter material (North East UK), significant quantities have arisen that have little commercial value. The filter manufacturers have been looking for another outlet for their product and polypropylene fibre ...

A stable and accurate control-volume technique based on integrated radial basis function networks for fluid-flow problems [PDF]

open access: yes, 2011
Radial basis function networks (RBFNs) have been widely used in solving partial differential equations as they are able to provide fast convergence.

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.
