Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

Passive Shock Isolation Utilising Dry Friction

open access: yesShock and Vibration, 2017
A novel shock isolation strategy for base excited system is presented by introducing a two-degree-of-freedom model with passive friction, where the friction is applied to an attached mass instead of directly to the primary isolated mass.

Stick-slip motion of a two-dimensional coupled dry friction oscillator

open access: yesJournal of Hebei University of Science and Technology, 2018
In view of the widely existed two-dimensional friction problems in engineering, an oscillator model which considers the coupling of and direction is established by introducing oblique springs.

Experimental Investigation on Synergetic Effects of Micro Grooves and WSe2 in Sliding Contact

open access: yesLubricants, 2022
Improving tribological behaviors for dry contacts has always been a hot study topic, since liquid lubricants are not applicable for certain vital scenarios, including space travel equipment.

On the calculation of a dry friction coefficient [PDF]

open access: yesPAMM, 2019
AbstractNormal contact problems of rough surfaces have already been extensively investigated. For Gaussian surfaces, the normal force Fn is often found to be proportional to the real contact area A. Following the approach of Bowden and Tabor [1] for the tangential force Ft = τA, where τ denotes the yield shear stress of the softer surface, the friction

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

FRICTIONAL BEHAVIOUR OF BARE FOOT AND RUBBER FOOTWEAR SOLE SLIDING AGAINST POLYPROPYLENE BRAKE PEDAL PADS [PDF]

open access: yesJournal of the Egyptian Society of Tribology, 2011
The present work discusses the friction coefficient displayed by bare foot and footwear soles sliding against polypropylene brake pedal pads. The frictional performance is compared to that obtained from the rubber conventional pads.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

open access: yesAdvanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...
