“…Two different batch-type mixers were employed, an internal batch mixer (B) and a high-shear kneading mixer (H). A rotor-mixer (Rheocomp ® 600, MKE, Daejeon, Korea) was used as an internal batch mixer (B), and a high-shear processing machine (NHS 2-28; Niigata Machine Techno Co., Ltd., Niigata, Japan [ 20 ]) was used as the high-shear kneading mixer (H). The high-shear processing machine is composed of two sections; a plasticization–injection section that plasticizes the resin and injects an arbitrary amount, and a high-shear kneading section.…”

“…For this purpose, a different mixing process is employed, with two batch-type mixers having different screw configuration and rotation speed. In this study, a typical internal batch mixer and a high-shear kneading mixer are used [ 20 ]. The mixing sequence is designed to distinguish the blend morphology evolution from the particle dispersion during the mixing process.…”

Effect of Melt-Compounding Protocol on Self-Aggregation and Percolation in a Ternary Composite

A ternary composite of poly(lactic acid) (PLA), poly(caprolactone) (PCL), and carbon black (CB) shows the PCL-induced CB self-aggregation and percolation formation when the amount of the PCL phase as the secondary phase is as small as the amount of CB. Furthermore, when the drop size of the PCL phase becomes smaller, the ternary composite forms a percolation of high order structure, resulting in a remarkable enhancement of the electrical conductivity (~4 × 10−2 S/m with 4 wt.% CB). To further control the percolation structure, the composite fabrication is controlled by splitting a typical single-step mixing process into two steps, focusing on the dispersion of the secondary PCL phase and the CB particles separately. Under the single-step mixing protocol, the ternary composite shows a structure with greater CB aggregation in the form of a high aspect ratio and large aggregates (aggregate perimeter~aggregate size 0.7). Meanwhile, the two-step mixing process causes the CB aggregates to expand and create a higher structure (aggregate perimeter~aggregate size 0.8). The reduced size of the secondary phase under a mixing condition with high shear force prior to the addition of CB provides a larger interfacial area for CB to diffuse into the PCL phase during the subsequent mixing step, resulting in a further expansion of CB aggregation throughout the composite. The particle percolation of such a high order structure is attributed to high storage modulus (G′), high Young’s modulus, high dielectric loss (ε″), and negative–positive switching of dielectric constant at high frequency (of 103 Hz) of composite.

“…The HSP is a batch-type kneading machine and has a special screw with a small hole in the center (return hole). Hence, it is possible to knead a certain amount of resin at arbitrary rotation speed and time [6][7][8][9]. The samples after kneading were pelletized, and then molded to three-point bending test pieces and flat plate test pieces using the injection molding machine.…”

“…The compacted samples are then tested on schedule according to the related standard to the test in various experiments. In the present study, 7% void was used for the compaction of indirect tension samples, and the control of number of rotation was used for other samples [22][23]. Finally, ten types of modified bitumen, along with a kind of non-modified bitumen, were prepared.…”

The main objective of this research is to investigate the rutting of modified mixtures with two additives of crumb rubber and polyethylene terephthalate (PET).Therefore, ITS method, resilient modulus and Dynamic creep were used to investigate asphalt behaviour with these two additives in this article. Modified blends include ten blends that are made by combining crumb rubber and polyethylene terephthalate in various percentages. The modifiers are combined in two percent 10% and 15% with 60/70 penetration bitumen. Finally, with these mentioned tests, the results of the ten modified samples along with the non-modified one were compared. The results showed that the addition of polyethylene terephthalate increased the viscosity and reduced the density; therefore, addition of more polyethylene terephthalate in the modifier reduces the flow number and, on the other hand, addition of 15% modifier containing polyethylene terephthalate resilient module increases the flow number by about 66%. Ultimately, neural network method was used to predict the result of dynamic creep test; indirect tensile strength and the capability of neural network method have been measured to estimate the laboratory result. According to the results, ANFIS can estimate the laboratory data correctly.
