“…It is interesting to point out that such variations in the mechanical properties can be detected, when using microsized fillers, only with much higher amounts (∼40 wt %) 51. This further proves the better interfacial interaction between matrix and filler assured by the nanosized particles here investigated.…”

The increase of the interest in polymer nanocomposites has been leading to continuous growing search toward nanofillers alternative to the widely known clay‐based ones. One of these possible alternatives is represented by calcium carbonate nanoparticles, which have not been widely investigated in such context. In this article, a study on the rheological and morphological behavior of different low density polyethylene‐calcium carbonate nanocomposites, compared with a reference calcium carbonate microcomposite, is presented. Several different nanosized calcium carbonates at different amounts were used. The results from the rheological and mechanical tests outlined that only minor changes occur when the amount is up to 2 wt %. The use of higher filler concentrations or the increase in the processing time can significantly affect this behavior. SEM analysis allowed deeper understanding of these phenomena. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

“…At loadings above 0.14 volume fraction, the elongation behavior remained near asymptotic. This value was in agreement with others reported for talc‐filled polymer systems (Li et al28 found the threshold value for filler loading ( V critical ) = 0.14) and elsewhere21, 39 in the literature (0.10 < V critical < 0.50). The transition near V f = 0.14 signified a change from ductile to quasibrittle behavior.…”

A reactive ethylene terpolymer (RET) with inorganic fillers of clay, talc, and zinc was examined for its cathodic disbondment (CD) performance and as a potential coating primer material for pipeline applications. The filler type and volume fraction influenced the mechanical, thermal, adhesion, and CD resistance of the coatings. The tensile modulus and strength of the RETs increased at higher loadings of selected fillers. The dry adhesive strength of the clay-filled RET maintained the same level of adhesion up to approximately 23 vol %, whereas the talc-and zinc-filled RETs showed decreases in adhesive performance. CD resistance was significantly improved with 18-23 vol % clay, whereas the overall disbondment area was reduced approximately 82% from pure RET. However, the post-cathodic-disbondment adhesive strength for the clay-filled RET decreased as a result of the degradation of the primer/ topcoat interface caused by moisture absorption.

“…In these environments, composites are engineered with increasing strength and with components at scales from micron fibres to nanoscale carbon inclusions [3,4]. Further, understanding of the dynamic response of polymers and polymer matrix composites at high pressures and strain rates is vital to fully describe the response of structures [5][6][7][8][9][10][11][12].…”

On the Shock Response of Polymers to Extreme Loading

This paper reviews polymer response to shock and discusses how plastics behave differently depending on the strain rate applied. The author uses polyethylene, polytetrafluroethylene, polycarbonate and epoxy as example materials. It is suggested that there are two distinct regimes of polymer response corresponding to low and high shock pressures (weak and strong shock regimes) that must be considered separately. Above a high pressure threshold it is proposed that polymers homogenize to carbon-containing structures which behave similarly. Further, the yield stress of a polymer volume element asymptotes to the theoretical strength of the material as volume shrinks to zero. It is suggested that these two behaviours reflect the same physics and this feature is common to the condition identified earlier for crystalline materials.
