“…That trend was similar to many Polymer Matrix Composites (PMCs) under a tensile loading [30,31]. Generally, in compression, filler may produce an increase in the ultimate compression strength of the polymer composite, where compression tends to close cracks and flaws that are perpendicular to the applied stress; and therefore, increase the compressive strength [32,33]. However, the strength of two-phase composites is still highly dependent on the effectiveness of the stress transfer between filler and matrix.…”

“…[19][20][21] Several studies on the influence of increasing volume fractions of ground micrometer-sized CaCO 3 fillers on the mechanical properties of polyolefins, especially on those of PP, have been reported. [22][23][24] In this study, attention was directed to the investigation of the role of CaCO 3 particles as reinforcing filler and as an extender for PLA composites. PLAN, PLAC, and PLAH were prepared by melt-compounding PLA with nanosized CaCO 3 pristine particles 2-5 lm in diameter, and CaCO 3 particles 3-4 lm in diameter coated with calcium stearate, respectively.…”

Poly(L-lactide) (PLA) was melt-mixed with micrometer-sized and nanosized calcium carbonate (CaCO 3 ) particles before and after modification with calcium stearate. Adhesion between the CaCO 3 particles and the PLA matrix was assessed qualitatively by scanning electron microscopy observation of the fractured surface morphology of the composites. The effect of the incorporation of the CaCO 3 particles on the thermal stability of the PLA-based composites was quantified by the temperatures corresponding to 5 and 50% of weight loss and the activation energy determined through thermogravimetric analyses of the composites. The tensile strength and modulus values of the composite were improved greatly without a significant loss in the elongation at break when the nanosized CaCO 3 was incorporated up to 30 wt %.

“…[1][2][3][4][5][6] The addition of inorganic fillers or particles to a polymer has been a common practice to improve the mechanical properties. Among inorganic fillers, calcium carbonate has been one of the most commonly used fillers for commodity plastics such as HDPE 6 and polypropylene (PP), 7 to reduce the cost of the expensive resins. It would be worth noting that these additions also incur a performance cost.…”

A study on high performance poly(etherether-ketone) (PEEK) composites prepared by incorporating aluminum oxide (Al 2 O 3 ), 0 to 50 wt % by hot compaction at 15 MPa and 350°C was described. Density, thermogravimetric analysis/differential scanning calorimetry, and scanning electron microscopy (SEM) were employed to evaluate their density, thermal stability, crystallinity, and morphology. Experimental density was found higher than theoretical density, which indicates that composite samples are sound. It was found that the addition of micron sized (Ͻ 15 m) Al 2 O 3 increased the peak crystallization temperature by 12°C when compared with neat PEEK with insignificant increase in melting temperature. Half-time of crystallization is reduced from 2.05 min for the neat PEEK to 1.08 min for PEEK incorporated with 30 wt % Al 2 O 3 because of the strong nucleation effect of Al 2 O 3 . The thermal stability of composites in air atmosphere was increased by 26°C. However, thermal stability in nitrogen atmosphere decreases at lower concentration of Al 2 O 3 but increases above 20 wt % of Al 2 O 3 . Uniform dispersion of Al 2 O 3 particles was observed in PEEK polymer matrix by SEM.
