transcrystallized interphase in thermoplastic composites part ii influence of interfacial stress cooling rate fibre properties and polymer molecular weight
Journal of Materials Science, 1992Co-Authors: J L Thomason, A A Van RooyenAbstract:Application of stress at the interface between a fibre and a supercooled polymer melt results in the growth of a transcrystallized interphase, independent of fibre type and Crystallization Temperature. This is in direct contrast to results obtained from quiescent Crystallization, where the occurrence of transCrystallization does depend on fibre type and Crystallization Temperature

transcrystallized interphase in thermoplastic composites part i influence of fibre type and Crystallization Temperature
Journal of Materials Science, 1992Co-Authors: J L Thomason, A A Van RooyenAbstract:Hot-stage microscopy and differential scanning calorimetry were used to investigate the isothermal Crystallization of polypropylene in the presence of a large variety of fibres. The occurrence of transCrystallization was found to depend on the type of fibre used and the Crystallization Temperature. The list of fibres which transcrystallize polypropylene is similar to that for other semicrystalline thermoplastics. In particular we found that aramid fibres and high-modulus carbon fibres do induce transCrystallization, whereas high-strength carbon fibres and glass fibres do not transcrystallize polypropylene

Crystallization Temperature vapor pressure density and viscosity of lithium bromide lithium iodide ethylene glycol water system for absorption refrigerators for automotive use
International Journal of Refrigeration-revue Internationale Du Froid, 2019Co-Authors: Takaaki Inada, Hiroyuki Tomita, Fumio Takemura, Osamu Tsubouchi, Eiji HiharaAbstract:Abstract Absorption refrigerators are expected for automotive use due to their advantage of utilizing waste heat from exhaust gas. The compactness and efficiency of the refrigeration system required for such use indicates a pair of water/lithium bromide (LiBr) as a promising working fluid. However, operation of absorption refrigerators for automotive use would be hampered by the Crystallization of LiBr solution, because relatively high concentration of LiBr solution is necessary for automotive use in which the absorber should be air-cooled. Therefore, the Crystallization Temperature of LiBr solution needs to be reduced. In this study, we focused on LiBr + lithium iodide (LiI) + ethylene glycol (C2H4(OH)2) aqueous solution as an absorbent, due to its lower Crystallization Temperature compared with LiBr solution. We measured the Crystallization Temperature, saturated vapor pressure, density and viscosity of these solutions with different composition ratios. The measured saturated vapor pressure, density and viscosity were then correlated using proper regression equations.

Crystallization Temperature vapor pressure density viscosity and specific heat capacity of the lino3 bmim cl h2o ternary system
Journal of Chemical & Engineering Data, 2017Co-Authors: Chunhua Luo, Kang CheAbstract:The Crystallization Temperature, vapor pressure, density, viscosity, and specific heat capacity for the ternary system of LiNO3/[BMIM]Cl/H2O with a mass ratio (LiNO3:[BMIM]Cl) of 2:1 were measured. The Crystallization Temperature was measured from w = 0.65 to 0.75. The vapor pressure was measured from w = 0.55 to 0.75 and 298.15 to 416.45 K. The density, viscosity, and specific heat capacity were measured from w = 0.55 to 0.75 and 293.15 to 373.15 K. Regression equations for the measured values were obtained by a least-squares method. Results showed that LiNO3/[BMIM]Cl/H2O had vapor pressure nearly identical to that for LiNO3/H2O at a 10% lower mass fraction. The Crystallization Temperature for LiNO3/[BMIM]Cl/H2O was much lower than that for LiNO3/H2O with the same absorption ability. LiNO3/[BMIM]Cl/H2O has a great potential as an alternative working pair.
