Structural and mechanical behavior of layered zirconium phosphonate as a distributed phase in polycaprolactone
(Wiley Subscription Services, Inc., A Wiley Company, 2009-10-15)
Mixed-surface octyl/methoxyundecyl Α-zirconium phosphonates (ZrPs) were investigated as distributed nanoscale fillers, in concentrations up to 50% w/w, for the purpose of increasing the elastic modulus and yield strength ...
Ultrasonic measurements of the elastic moduli of liquid crystalline polymers
(Elsevier, 1992)
The five independent elastic moduli of extruded rods of two thermotropic liquid crystalline polymers, Vectra B900 and Vectra A950, and the nine independent moduli of an injection-moulded bar of Vectra A950 have been measured ...
The preparation and morphology of PPO–epoxy blends
(Wiley Subscription Services, Inc., A Wiley Company, 1993-05-10)
Poly(phenylene oxide) (PPO) was found to be miscible in diglycidyl ether of bisphenol A (DGEBA) based epoxy. The PPO–DGEBA system exhibited upper critical solution temperature (UCST) behavior. The cloud point temperatures ...
Fatigue craze initiation in polycarbonate: study by small-angle X-ray scattering
(Elsevier, 1994-09)
The structural changes that occur during the incubation stage of tensile fatigue failure of glassy polycarbonate are investigated by means of small-angle X-ray scattering. The results are interpreted as the formation of ...
Preparation and characterization of maleimide-terminated poly(arylene ether sulfone) oligomers of various molecular weights
(Wiley Subscription Services, Inc., A Wiley Company, 1991-11-20)
A new variation in the bismaleimide (BMI) resin family, maleimide-terminated poly(oxy-1,4-phenylene sulfonyl-1,4-phenylene) oligomers, has been synthesized. The preparation of oligomers ( n = 1–12) is described in this ...
The effect of fiber orientation on the toughening of short fiber-reinforced polymers
(Wiley Subscription Services, Inc., A Wiley Company, 2003-12-05)
The effect of fiber orientation on the toughening of polymers by short glass fibers generally below their critical length was investigated using specimens with either well-aligned or randomly oriented fibers. The fibers ...
Microstructural deformation behaviour in polystyrene-based compatible polymer blend systems
(Elsevier, 1994-05)
Microstructural deformation behaviour in polystyrene-based compatible polymer blend systems was studied using transmission electron microscopy (TEM) and microdensitometry. Four different binary compatible blend systems ...
Mechanical properties of polyurethane/montmorillonite nanocomposite prepared by melt mixing
(Wiley Subscription Services, Inc., A Wiley Company, 2007-10-05)
Nanocomposites from polyurethane (PU) and montmorillonite (MMT) were prepared under melt-mixing condition, by a twin screw extruder along with a compatibilizer to enhance dispersion of MMT. MMT used in this study was ...
Toughening mechanisms in thermoplastic-modified epoxies: 1. Modification using poly(phenylene oxide)
(Elsevier, 1993-09)
An epoxy based on the diglycidyl ether of bisphenol A (DGEBA) has been modified with poly(phenylene oxide) (PPO) and cured with piperidine. A two-phase alloy resulted, in which the DGEBA epoxy was the continuous phase. ...
Fatigue craze initiation in polycarbonate: study by transmission electron microscopy
(Elsevier, 1994-08)
Fatigue craze initiation in bulk, amorphous polycarbonate (PC) is investigated by means of transmission electron microscopy. The results agree very well with small angle X-ray scattering measurements of the same set of ...
