Does a compatibilizer enhance the properties of carbon fiber-reinforced composites?
Prashant Gangwani, Mitjan Kalin, Nazanin Emami
Izvirni znanstveni članek
Oznake: kompatibilizatorji;ogljikova vlakna;polimerni kompoziti;compatibilizers;carbon fiber;polymer composites;UHMWPE;PTFE;PPS;
We have evaluated the effectiveness of compatibilizers in blends and composites produced using a solvent manufacturing process. The compatibilizers were two different types of polyethylene (linear low-density and high-density) grafted with maleic anhydride (MAH) and a highly functionalized, epoxy-ba ...

Development of new multiscale polymer composites for water lubricated tribological contacts
Hari Shankar Vadivel, Mitjan Kalin, Nazanin Emami
Doktorska disertacija
Oznake: dissertations;UHMWPE;composites;tribology;viscoelasticity;thermomechanical;
Moving towards a Green Economy, there is a growing demand to use environmentally friendly tribological systems that has resulted in industries turning towards new materials and water-based lubrication to satisfy their needs. Considering the low viscosity of water, tribological contacts lubricated wi ...

Effect of multi-scale fillers on the tribological behavior of UHMWPE composites in water-lubricated contacts
Prashant Gangwani, Janez Kovač, Nazanin Emami, Mitjan Kalin
Izvirni znanstveni članek
Oznake: multi-scale;fillers;UHMWPE;composites;water;tribology;
This study investigates the impact of graphite, hexagonal boron nitride and short carbon fibers, acting as micro- and nano-fillers, on the tribological performance of ultra-high-molecular-weight polyethylene (UHMWPE) hybrid composites. The tribological performance is evaluated under boundary-lubrica ...

Tribological performance of a UHMWPE-based multiscale composite under different lubrication and loads
Hari Shankar Vadivel, Julian Somberg, Mitjan Kalin, Nazanin Emami
Izvirni znanstveni članek
Oznake: lubrication;multiscale composites;transfer;UHMWPE;friction;wear;
An UHMWPE-based multiscale composite containing graphene oxide, nanodiamonds, and short carbon fibres has shown excellent performance under distilled water lubrication. However, it is crucial to evaluate its tribological performance under conditions which more accurately represent the final applicat ...

Mechanical properties and tribological performance of polyoxymethylene/short cellulose fiber composites
Lucas M. Kneissl, Gil Gonçalves, Roberts Joffe, Mitjan Kalin, Nazanin Emami
Izvirni znanstveni članek
Oznake: polyoxymethylene;cellulose fibers;processing;characterization;tribology;
Natural fibers are promising bio-based materials to use as reinforcements in polymer composites as often more affordable and accessible alternatives to fossil-based fibers, especially because of their superior sustainability. Polyoxymethylene (POM) is a widely used engineering thermoplastic, which h ...

Time-dependent properties of newly developed multiscale UHMWPE composites
Hari Shankar Vadivel, Zainab Al-Maqdasi, Liva Pupure, Roberts Joffe, Mitjan Kalin, Nazanin Emami
Izvirni znanstveni članek
Oznake: ultra-high molecular-weight polyethylene;multiscale reinforcements;nanocomposite;creep;tensile strength;stiffness;
Ultra-high molecular-weight polyethylene (UHMWPE) composites reinforced with Graphene Oxide (GO), Nanodiamonds (ND), and Short Carbon Fibres (SCF) are characterised for their mechanical performance in tensile and short-term creep tests. A methodology to separate and analyse the materialsʼ viscoelast ...

Do the particle size, molecular weight, and processing of UHMWPE affect its thermomechanical and tribological performance?
Hari Shankar Vadivel, Marko Bek, Urška Šebenik, Lidija Slemenik Perše, R. Kádár, Nazanin Emami, Mitjan Kalin
Izvirni znanstveni članek
Oznake: UHMWPE;reologija;viskoelastičnost;tribologija;rheology;viscoelasticity;tribology;
UHMWPE has exhibited excellent performance when used as contact surfaces in tribological contacts. Traditionally, only UHMWPE grades, with narrow particle size and molecular weight distribution, have been deemed suitable for such applications. Now, various UHMWPE grades are available that are differ ...
