Interlocked CNT networks with high damping and storage modulus
Carbon, 2015The interlocked carbon nanotube (CNT) networks formed by floating catalyst chemical vapor deposition method is found to show greatly enhanced damping ratio (0.37-0.42) and much higher storage modulus (>11.0 GPa) compared to most of engineering damping materials and any other kinds of CNT networks and composites ever reported. Interestingly, its damping

Molecular weight of linear polymer from storage modulus
Journal of Macromolecular Science, Part B, 1992Abstract In a previous work [1], using a binary blending rule, we had developed a numerical method to calculate the polymer molecular weight from the relaxation time spectrum of the terminal zone of stress relaxation modulus G(t). In this work, we separated the terminal zone of storage modulus G'(ω) from plateau modulus Gno and calculated the ...

High-temperature strength and storage modulus in unidirectional hybrid composites
Composites Science and Technology, 2006Abstract The mechanical properties of pultruded rods of unidirectional hybrid glass/carbon-epoxy composites were evaluated with respect to retention of high-temperature properties up to 250 °C. Two prototype matrices were produced using developmental epoxy formulations with glass transition temperatures (Tg) of 176 and 202 °C, respectively.

Weibull distribution application on temperature dependence of polyurethane storage modulus
International Journal of Materials Research, 2016Abstract In this paper, a stiffness–temperature model based on Weibull statistics was applied to quantitatively describe changes in the storage modulus of thermoplastic polyurethane over a wide range of temperature. The variation of the storage modulus with temperature was obtained from dynamic mechanical analysis tests across transition

Storage Modulus Analysis of Kenaf Fibre Reinforced Epoxy Composites
Applied Mechanics and Materials, 2013This article presents the storage modulus analysis of kenaf fibre composites that reinforced by two different epoxy matrix systems, named epoxy A and epoxy B. These epoxies are commercially available in Malaysia and been used as a polymer matrix in composite research.

The uniaxial tensile moduli for two filled composite solid propellants, one based on a hydroxy-terminated polybutadiene with an ammonium perchlorate oxidizer and the other on a glycidyl azide polymer with a phase-stabilized ammonium nitrate oxidizer, were measured at various temperatures and over a three decade range of strain rates.

Langmuir, 2016
Atomic force microscopy (AFM) is used to carry out rheology measurements on the nanoscale and to determine the mechanical properties of poly(l-lysine) (PLL)/hyaluronic acid (HA) multilayer films. Storage (G') and loss modulus (G″) of the films are calculated and compared with the values obtained from quartz crystal microbalance with dissipation ...

A New Temperature-Dependent Storage Modulus Model of Epoxy Resin
2016Temperature-dependent dynamic mechanical properties of epoxy resin were studied by dynamic mechanical analysis. A new temperature-dependent storage modulus model was developed to describe the storage modulus of epoxy resin for multi-transition regions from cryogenics to elevated temperatures.

Rheology of PVC Plastisol—V: Storage Modulus and Network Formed by Particle Contact
Journal of Colloid and Interface Science, 2002Our previous work with PVC plastisols showed that pseudo-plastic behavior under increasing frequency of dynamic measurement was a result of the development of an immobilized layer. Subsequently, the dynamic viscosity and the storage modulus of the mobile phase were evaluated.
