The same type of curve would have been generated in the dilatometry
experiment, had the coefficient of thermal expansion been plotted against temperature.
Topics covered include Differential Scanning Calorimetry and Differential Thermal Analysis (DSC/DTA), Thermogravimetry, Thermomechanical Analysis and Dilatometry
, Dynamic Mechanical Analysis, Micro-Thermal Analysis, Hot Stage Microscopy, and Instrumentation.
Traditionally, the solid fat index was calculated using dilatometry
but this is an awkward technique, and the results can be imprecise and subjective.
Another means of examining fundamental thermodynamic phenomena is the use of high-pressure dilatometry
to measure the pressure-volume-temperature dependence of polymers.
In addition, pressure dilatometry
measurements were used to calculate the equation of state parameters for the polybutadienes.
Comparison of turbidity and dilatometry
data (47), (49) has shown that the relative volume crystallinity detectable by turbidity is well below 0.
The results of thermal analysis, dilatometry
, birefringence, sonic measurements and x-ray scattering are given in table 2.
Determination of residual stresses arising from volumetric shrinkage of epoxy and unsaturated polyester resins has been extensively reported using methods such as dilatometry
(6-8), torsional parallel plate rheometry (9), dynamic mechanical analysis , bending beam [11, 12], and changes in buoyancy of the resin (2), (5), (13), (14).
The hybrids were further characterized by scanning electron microscopy (SEM), FTIR, dilatometry
, and thermogravimetric analysis (TGA).
For subsequent analyses including dilatometry
tests, different types of specimens were obtained by compaction of the raw powders following to two different routes.
The analysis of SEM results, as well as of the measurements of density, moisture content, dilatometry
, and mechanical tests gives us grounds to assume that for the used [epsilon] values, the structure rearrangements occur in the amorphous phase under ED and in the crystalline phase under ECMAE.
