Experimental assesment of infrared welded bonds using lapshear, double cantilever beam and end notch flexure tests for a carbon fabric reinforced thermoplastic [PDF]

, 2012
High performance composites, such as carbon-fibre reinforced plastics (CFRP), are increasingly being used in high engineering industries. Their wide acceptance introduces an issue regarding the bonding of these materials and their mechanical behaviour ...

The influence of toughening-particles in CFRPs on low velocity impact damage resistance performance

, 2014
The role of particle-toughening for increasing impact damage resistance in carbon fibre reinforced polymer (CFRP) composites was investigated. Five carbon fibre reinforced systems consisting of four particle-toughened matrices and one system containing ...

Vpliv podhlajevanja na lomno žilavost martenzitnega nerjavečega jekla AISI 420 [PDF]

, 2017
Cryogenic treatments have been employed over the last three decades in both tool and high-alloy steels to improve wear resistance, mainly through the transformation of retained austenite and the precipitation of fine carbides.

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

Effect of MTA and Portland Cement on Fracture Resistance of Dentin

Journal of Dental Research, Dental Clinics, Dental Prospects, 2013
Background and aims. It is important to evaluate the effects of endodontic materials on tooth structures to avoid endodontic treatment failure. The aim of the present study was to investigate the effect of mineral trioxide aggregates (MTA) and Portland

Study of SENT specimens with a tilted notch to evaluate ductile tearing in spiral welded pipeline applications [PDF]

, 2015
There is an increasing interest for the use of spiral welded pipelines in strain based design applications. Environmentally imposed loads are able to plastically deform the pipelines, meaning that their structural response is of the utmost importance ...

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Microstructured Thin Film Nitinol for a Neurovascular Flow-Diverter [PDF]

, 2016
A cerebral aneurysm occurs as a result of a weakened blood vessel, which allows blood to flow into a sac or a ballooned section. Recent advancement shows that a new device, ‘flow-diverter’, can divert blood flow away from the aneurysm sac.
