Large volume, high-performance applications of fibers in civil engineering
(Wiley Periodicals, Inc., 2002-01-18)
This article presents an overview of fiber applications in cementitious composites. The socio-economic considerations surrounding materials development in civil engineering in general, and fiber reinforced cementitious ...
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 ...
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 ...
Effects of surface modification, carbon nanofiber concentration, and dispersion time on the mechanical properties of carbon-nanofiber–polycarbonate composites
(Wiley Subscription Services, Inc., A Wiley Company, 2007-03-15)
The time effect of ultrasonication was investigated for dispersing carbon nanofibers (CNFs) into a polycarbonate (PC) matrix on the mechanical properties of thus-produced composites. The effects of CNF surface modification ...
At-column heating and a resistively heated, liquid-cooled thermal modulator for a low-resource bench-top GC×GC
(WILEY-VCH Verlag, 2006-05)
A transportable GC×GC instrument is under development for on-site applications that would benefit from the enhanced resolution and powers of detection, which can be achieved by this method. In the present study, a low-resource ...
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 ...
Performance characteristics of a new prototype for a portable GC using ambient air as carrier gas for on-site analysis
(WILEY-VCH Verlag, 2007-05)
The performance characteristics of a portable GC instrument requiring no compressed gas supplies and using relatively lightweight transportable components for the analysis of volatile organic components in large-volume air ...
Fracture behavior of glass bead filled epoxies: Cleaning process of glass beads
(John Wiley & Sons, Inc., 2001-02-22)
Inorganic particles are commonly cleaned with solvents such as alcohols before being incorporated into thermoset polymers as fillers or tougheners, but the role of the cleaning process has never been examined. In this ...
