Although the scratch test has now become commonplace both in the research field as a
measurement tool and in industry as a Quality Control (QC) tool, the utility of this technique …

To study the effects of surface roughness and contact load on the friction behavior and
scratch resistance of polymers, a set of model thermoplastic olefins (TPO) systems with …

Laser-powder bed fusion was identified as a promising technique for manufacturing metal
matrix composites. However, over a decade later, little progress has been made in …

The aim of this study was to relate the scratching behaviour of polymers to their mechanical
properties. A thermosetting resin (CR39) and a thermoplastic polymer (PMMA) were studied …

Epoxy-based nanocomposites were prepared with the addition of poly (ethyleneimine)(PEI,
an amine-riched polymer) functionalized multi-walled carbon nanotubes (MWCNTs), whose …

Compared to the experimental studies, numerical studies on scratch test have been limited
due to the difficulty of numerical modeling. Here, we experimentally investigate the scratch …

In nanoscratch testing, it is generally observed that the lateral force does not linearly
increase with the applied load. In other words, the apparent friction coefficient, defined as …

The current analytical models are insufficient to describe the ploughing part of the friction
coefficient when there is elastic recovery at the rear part of the contact after passage of a …

Rockwell C diamond indenter with a spherical tip of radius of 108 μm was used to slide on
bulk polycarbonate under linearly increasing normal load from 5 mN to 20 N in order to …

Carbon fiber reinforced polymers (CFRP) are increasingly employed within the aerospace
industry, particularly within the aircraft sector. However, machining of fiber reinforced …
