On the overall elastic moduli of polymer–clay nanocomposite materials using a self-consistent approach. Part II: Experimental verification

Elastic and yield behaviors of recycled polypropylene-based composites: Experimental and modeling study

“…3, the compressive Young's modulus, E, of neat PP had a continuous decrease with reprocessing cycles. Therefore, we assumed a linear evolution of Young's modulus for neat PP with reprocessing: (12) where N p is the number of reprocessing, k 1 is the reprocessing strengthening coefficient of Young's modulus for neat PP, and E 0 is the Young's modulus for non-recycled neat PP. For PP/EOC and PP/Talc composites, we found an evolution of the aspect ratio (AR) of EOC and talc particle dimensions with the reprocessing cycles in our previous studies (due to the important shear stress of extrusion) [9,10].…”

Prediction of Young’s modulus: from effective clay clusters to polymer nanocomposites

“…It was shown (Figure 3) that there is a good agreement between the calculated and measured results by Anoukou et al [4] The Young's modulus increases with the volume fraction of silicate (i.e., montmorillonite). Moreover, the calculated Young's modili of polymer with partially exfoliated clay clusters are closer to the measurements.…”

Molecular dynamics studies on the overall compressive modulus of nylon 6/montmorillonite nanocomposites

“…As can be observed from Figure 6, the same and even ratios of angle u were applied to both fully and partially exfoliated morphologies. However, Anoukou et al 4 have reported that the clay platelets are dispersed in random angles when fully exfoliated clay platelet predominates in the nanocomposites; thus, our simulation data took the percentages of angles 0°, 30°, 45°, 60°and 90°as occupied by 30%, 30%, 0%, 20% and 20%, respectively. Moreover, the clay platelets are mainly located parallel to the applied force when partially exfoliated structures start to occur (i.e.…”

“…This conclusion has been well recognised that fully exfoliated morphology exhibits the largest mechanical properties. 4,5 Overall compressive moduli of nylon 6/MMT nanocomposites when distribution of angle u is arbitrarily assigned and based on experimental observation…”

“…elastic moduli), [1][2][3][4][5][6] greatly improved thermal stability, 7,8 excellent gas barrier properties 9,10 and dielectric properties. 11,12 Among these fantastic properties of polymer/clay nanocomposites, enhanced mechanical properties have attracted a lot of interest and attention.…”
