MELTING BEHAVIOR OF NYLON 66

Investigation of Mechanical Properties Prediction of Synthesized Nylon-66/Nano-Calcium Carbonate Composites

In this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. Mechanical properties of micro and nano- composites, including tensile strength, elongation, and Young’s modulus, before and after ageing, were determined and analyzed. For this purpose, micro- and nano-sized CaCO3 particles were used as fillers to prepare micro-composites (c...

Fracture Behavior of Nylon Hybrid Composites

Gas Holdup Behavior in Nylon Fiber Suspensions

The gas holdup behavior in a nylon fiber suspension with various fiber lengths (L = 2, 3, and 6 mm) is investigated. Experiments are performed over a range of superficial gas velocities (Ug≤ 18 cm/s) and a range of fiber mass fractions (0 ≤ C ≤ 1.8%) in a 15.24-cm-diameter semibatch bubble column. Day-to-day variations in the gas holdup create difficulties in interpreting the effect of the fibe...

Atomic Insights into the Melting Behavior of Metallic Nano-catalysts

In the present study, molecular dynamics simulations have been utilized to provide fundamental understanding of melting behavior of pure Pd and Pt nanoparticles with the size of 10 nm in diameter, both free and graphene-supported during continuous heating. The embedded atom method is employed to model the metal-metal interactions, whereas a Lennard-Jones potential is applied to describe the met...

Structure Development during the Heat-Draw Process of Nylon 66 Fiber by Synchrotron X-ray Diffraction

On-line studies of structural development during continuous drawing of nylon 66 fiber at different temperatures were carried out using synchrotron wide-angle X-ray diffraction (WAXD). A unique image analysis method was introduced to analyze the two-dimensional (2D) WAXD patterns. The quantitative fractions of crystal, mesomorphic and amorphous phases were obtained. In this study, the Brill tran...
