Previous studies of polyolefin/CB composites have reported modest enhancement to major reduction in modulus and major reduction in elongation at break values relative to neat polymer.
While all nanotubes contributed to property improvements, maximum increase in modulus (75%) and reduction in thermal shrinkage (up to 50%) was observed in the SWNT containing composites, and the maximum improvement in tensile strength (70%), strain to failure (110%), and work of rupture (230%) was observed in the MWNTs containing composites.
The results from this investigation provided post-fire stress-strain curves, yield strengths, ultimate strengths and elastic modulus, and their reduction pattern.
The effects of material selections and stiff material fraction on the Poisson's ratio, equivalent Young's Modulus, and maximum volume reduction were investigated.
With incorporation of as low as 0.3 wt% of SGO, a 100% increase in the tensile strength, a 66% improvement in the tensile modulus and a 48% reduction in the air permeability are achieved without sacrificing the ultimate strain.
It has been shown that a uniaxial tensile stress applied to the preform results in an increase in tensile modulus and a corresponding reduction in the transverse modulus, as a result of reduced crimp in the loading direction with a corresponding increase in the transverse direction.
On comparing the results with those obtained from specimens tested without conditioning and immersion and employing Huet-Sayegh's rheological model with the introduction of the damage factor (D), it was possible to evaluate the effect of the action of water and temperature on the graphical representation of the complex modulus and on the reduction in the fatigue life of the asphalt mixture.
All EDC-modified at standard cross-linking condition (11.5 mg/ml EDC, 100%) matrices displayed the highest Young's Modulus and 10-fold reduction in EDC/NHS concentrations still provides good mechanical stability for Col-containing scaffolds compositions.
Therefore, although it showed the lowest temperature sensitivity in volume change, limestone aggregate and limestone concrete yielded the highest relative strength and modulus reduction among the three concretes.
