“…Ultimate elongation is also reduced in composites with mineral fillers; this phenomenon is known as "embrittlement". The criterion for transition between ductile and brittle deformation is described in publications [23][24][25][26]. If the composite's strength is larger than the stress of neck propagation, a neck appears and propagates throughout the working area of a tensile specimen (ductile type deformation).…”

The article describes a preparation method and performance behaviour of polymer composite systems with a matrix of LDPE and a reinforcing agent of taurit. Taurit (a species of shungite) is an inexpensive, well-available and environmentally friendly mineral, compatible with many polymers. The composites have been prepared via extrusion blending and their mechanical and protective properties have been studied. Performance of taurit-containing materials has been compared with properties of composites with other commonly used fillers (carbon black, talc, aluminium oxide, asbestos fibres, etc.) and taurit was proven to be the most efficient reinforcement in this series. The results indicate that the obtained composites can be used as coatings for pipelines to protect them from corrosion and mechanical damage.

Polyolefin composites were prepared from 14 PE matrices and three different mineral fillers (montmorillonite, palygorskite and glass microspheres) via melt compounding in an extruder. Mechanical properties of the obtained systems were analyzed with emphasis on elongation at break and conditions for ductile/brittle failure were determined. When filler content is raised beyond a certain "critical" value, tensile properties are dramatically altered and transition occurs from ductile behavior to brittle fracture. This transition is displayed by a well-defined "step" on the plot of strain at break versus concentration of particles. The value of "critical filler content" was found to depend mainly on level of crystallinity of a matrix while other parameters (chemical nature of filler particles, their size, shape and surface treatment) are less significant. "Critical filler content" will decrease with growth of crystallinity of a polymer and with highly crystalline HDPEs it is as low as 2-8 vol %. Otherwise, with noncrystallizing and low-crystalline polymers elongation at break decreases gradually with concentration of mineral particles and ductile type deformation is maintained at fairly large filler fractions. The results presented here will be useful for a proper selection of a matrix polymer in composites with mineral fillers.
