Effect of Water Aging on the Mechanical Properties of Hybrid Carbon/Aramid Reinforced Thermoplastic Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the mechanical properties of Carbon/Aramid intraply hybrid fiber‐reinforced Elium composites under 6 months of water aging. After aging, flexural strength decreases by 25.89%, tensile strength by 4.40%, and fracture toughness by 21.56%.

Thermal Healing, Reshaping and Ecofriendly Recycling of Epoxy Resin Crosslinked with Schiff Base of Vanillin and Hexane-1,6-Diamine

open access: yesPolymers, 2019
A bio-derived dihydroxylimine hardener, Van2HMDA, for the curing of epoxy resin was prepared from vanillin (Van) and hexamethylene-1,6-diamine (HMDA) by Schiff base formation.

Toughness of Confined Auxetic Foams

open access: yesAdvanced Engineering Materials, EarlyView.
Auxetic (negative Poisson's ratio) materials offer benefits such as impact mitigation, thermal insulation, vibration damping, and reduced shear strain, although their fracture mechanics are largely unexplored. This study investigates damage initiation and propagation in confined re‐entrant auxetic foams from polyurethane via experimental ...

Direct Natural and Artificial Aging of Aluminum Alloy AlSi10Mg After Laser Powder‐Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Laser powder‐bed fusion of metals aluminum alloy AlSi10Mg has been directly aged. Artificial aging after natural aging is considered. The hardening potential is high for the top part of the samples as well as after short natural aging. The hardening potential is substantially reduced for the bottom part of the samples, as well as after natural aging of

Hygrothermal ageing characterisation of epoxy resin based on transmission characteristics of microwave resonator with interdigital‐capacitor‐shaped defected ground structure

open access: yesHigh Voltage, 2023
In this article, a method is proposed for the characterisation of epoxy resin thermal and hygrothermal ageing based on microwave resonator with interdigital‐capacitor‐shaped defected ground structure (IDCS‐DGS), which can realise rapid and simple non ...

Joule‐Assisted Nanotherapeutic Urethral Stent (JANUS) for Spatiotemporal Theragenerative Treatment of Urethral Strictures

open access: yesAdvanced Functional Materials, EarlyView.
Joule‐assisted nanotherapeutic urethral stent harnesses a smart, biodegradable magnesium stent to orchestrate spatiotemporal theragenerative therapy for urethral strictures. Magnetically induced Joule heating enables on‐demand drug release and bacterial ablation, while simultaneously guiding urothelial regeneration.

Training performance of Nb3Sn Rutherford cables in a channel with a wide range of impregnation materials [PDF]

open access: yesarXiv, 2022
Training of accelerator magnets is a costly and time consuming process. The number of training quenches must therefore be reduced to a minimum. We investigate training of impregnated Nb3Sn Rutherford cable in a small-scale experiment. The test involves a Rutherford cable impregnated in a meandering channel simulating the environment of a canted-cosine ...
