Gas transport properties in polycarbonate - Influence of the cooling rate, physical aging, and orientation
… polymers is directly correlated with the free volume content. Free volume arguments are indeed commonly used to explain the gas transport process. The gas transport properties of bisphenol-A polycarbonate films were examined as a function of the cooling rate, physical aging, and orientation. …

Actuation of shape memory polymer using magnetic fields for applications in medical devices
… the mechanical effects of various particle volume contents and sizes on shape memory polymer. These tests suggest that the proposed method of actuation is very feasible, rapid heating can be achieved and the addition of particles up to 10% volume content has a minimal effect on the …

Sliding Wear of a Squeeze Cast Magnesium Composite AM60-(Al2O3)f at Low Loads
… high fibre length. Increasing the Al2O3 fibre volume content delayed the transition to higher rate of material loss but inflicted greater damage to the counterface. At 100 ░C, the formation of an oil residue layer on the worn surfaces delayed the wear transition.

Lyocell Fiber-Reinforced Cellulose Ester Composites - Surface and Consolidation Considerations, and Properties
… particles adhering to the fiber surfaces. Void volume formation was mitigated to a small extent by the use of optimal consolidation conditions. Composites formed at moderate temperature (200 °C), low consolidation pressure (11.8 p.s.i.) and high consolidation time (13 min.) were found to have …

Optimization of Polymer-based Nanocomposites for High Energy Density Applications
… unmodified polymer. The key is maintaining a low volume content to ensure a high inter-particle distance, effectively minimizing the effect of local field on the composite's dielectric breakdown. The first step is studying the particle size and aspect ratio effects on the dielectric properties to …

The effect of aggregate on the age at cracking of bonded concrete overlays subjected to restrained deformation
… is prone to failure due to differential volume changes between the newly cast repair material and the existing substrate. These volume changes can be attributed to thermal and shrinkage differences, with drying shrinkage being identified as they key source of the volume change. When the …

Freeze-thaw environment of precast concrete crossties and effect of vibration on fresh materials
… of distance from the vibrating source and the volume content of aggregate is studied and compared against the extent of air loss and aggregate segregation as evidenced in polished, 2-dimensional sections. Summarily, the mutual instances of critical moisture saturation and freezing temperatures …

Deformation and fracture of polycarbonate and rubber-modified polycarbonate under controlled temperature, deformation rate, and notch stress triaxiality
… are all seen to decrease with increasing rubber volume content. The inclusion of sub-micron rubber particles is shown not to dramatically enhance the mechanical properties of un-notched or mildly notched specimens. The inclusion of sub-micron rubber particles is shown to drastically increase the …
