The Halpin‐Tsai equations: A review
Tập 16 Số 5 - Trang 344-352 - 1976
AbstractThe Halpin‐Tsai equations are based upon the “self‐consistent
micromechanics method” developed by Hill. Hermans employed this model to obtain
a solution in terms of Hill's “reduced moduli”. Halpin and Tsai have reduced
Hermans' solution to a simpler analytical form and extended its use for a
variety of filament geometries. The development of these micromechanic's
relationships, which form ...
A method for estimating both the solubility parameters and molar volumes of liquids
Tập 14 Số 2 - Trang 147-154 - 1974
AbstractThe solubility parameters and molar volumes of substances can be used,
in conjunction with suitable theory, to provide estimates of the thermodynamic
properties of solutions; the solubility characteristics of polymer‐solvent
systems and the estimation of the equilibrium uptake of liquids by polymers are
examples of the type of practical problems that are amenable to treatment.For
low molec...
On the characterization of nonlinear viscoelastic materials
Tập 9 Số 4 - Trang 295-310 - 1969
AbstractStarting with specific constitutive equations, methods of evaluating
material properties from experimental data are outlined and then illustrated for
some polymeric materials; these equations have been derived from thermodynamic
principles, and are very similar to the Boltzmann superposition integral form of
linear theory. The experimental basis for two equations under uniaxial loading
and...
Nonisothermal melt and cold crystallization kinetics of poly(aryl ether ether ketone ketone)
Tập 37 Số 3 - Trang 568-575 - 1997
AbstractAnalysis of the nonisothermal melt and cold crystallization kinetics of
poly(aryl ether ether ketone ketone) (PEEKK) was performed by using differential
scanning calorimetry (DSC). The Avrami equation modified by Jeziorny could
describe only the primary stage of nonisothermal crystallization of PEEKK. And,
the Ozawa analysis, when applied to this polymer system, failed to describe its
noni...
Thermoset characterization for moldability analysis
Tập 14 Số 3 - Trang 231-239 - 1974
AbstractThe injection molding of thermosetting compounds involves complex
interactions between material parameters and molding conditions, on one hand,
and moldability and the ultimate properties of molded parts, on the other hand.
The main role of the molding variables may be related to their effects on the
cure time and temperature and on the flow and thermal phenomena that affect
orientation an...
A process for making microcellular thermoplastic parts
Tập 30 Số 20 - Trang 1323-1329 - 1990
AbstractA novel process to produce microcellular thermoplastic parts is
described. This is achieved by integrating the deformation process in the
foaming cycle in such a way that the cell nucleation and growth processes are
effectively uncoupled from deformation. The nitrogen‐polystyrene system is
studied and the relationships between the essential process parameters are
established. It is experim...
Physical aging in plastics and other glassy materials
Tập 17 Số 3 - Trang 165-173 - 1977
AbstractThis paper surveys the basic aspects of physical aging. It shows that
aging i s a general and important phenomenon found in all organic and inorganic
glasses and in some metals as well. Moreover, the behavior of all these
materials is very similar. It further shows that aging cannot be ignored in the
testing of plastics, particularly in the prediction of their long‐term behavior.
Mixed matrix membrane materials with glassy polymers. Part 1
Tập 42 Số 7 - Trang 1420-1431 - 2002
AbstractMixed matrix materials comprising molecular sieve entities embedded in a
polymer matrix can economically increase membrane permselectivity, thereby
addressing a key challenge hindering the widespread use of membrane‐based gas
separations. Prior work has clarified the importance of proper selection of the
dispersed sieve phase and the continuous matrix phase based on their intrinsic
transpo...
The determination of the fracture parameters for polymers in impact
Tập 15 Số 6 - Trang 470-477 - 1975
AbstractA method of analysis is given by which the critical strain energy
release rate Gc for impact tests may be deduced for both Charpy and Izod tests
from normal energy measurements. Suitable calibration factors are determined and
the method is applied to a range of polymers. Very close agreement is achieved
between the Charpy and Izod results except for highly ductile materials for
which it wa...
Dielectric and piezoelectric properties of PVDF/PZT composites: A review
Tập 55 Số 7 - Trang 1589-1616 - 2015
Smart materials, which exhibit piezoelectricity, find an eclectic range of
applications in the industry. The direct piezoelectric effect has been widely
used in sensor design, and the inverse piezoelectric effect has been applied in
actuator design. Ever since 1954, PZT and BaTiO3 were widely used for sensor and
actuator applications despite their toxicity, brittleness, inflexibility, etc.
With th...
