Thermal analysis is of limited use for such failures. However, in failure modes sensitive to the properties of the matrix resin, thermal analysis can help determine whether the matrix resin of a failed composite has the appropriate glass transition temperature T. Even if failure occurs at low temperatures, T should be checked for indications of overcure, g because an excessively high Tg can lead to microcracking. In addition, for a multiphase resin for example, elastomeric or thermoplastic modified , thermal analysis can determine the Tg of the modifying second phase.

If such a fingerprint differs to a significant degree from a control sample, there may be a problem with the composition of the modifier, the resin preparation for example, improper prereaction , the formulation too little or too much modifier , or the cure cycle.

For example, such changes in fingerprint could indicate that the modifiers are not acting to toughen the resin effectively, which could lead to low interlaminar toughness. It is therefore necessary to run a control specimen with a test specimen from the failed laminate. Ideally, the control laminate should be made from a batch of prepreg that is within composition specifications for which quality control data are available from both the manufacturer and the end user.

The control laminate lay-up should be of the same configuration as the failed laminate and should be done under controlled, or at least monitored, humidity.

Also, it should then be cured under the same cycle as was the test specimen. Then a thermal analysis can be performed, and the T and other transitions for both specimens can be compared. There are several reasons that T may be lower in the test laminate than in the g g control laminate.

The test laminate may have been undercured because an incorrect cure cycle was used. This sometimes occurs if the cure cycle is controlled using tool temperature rather than part temperature when the specified cycle is based on part temperature. The Tg also can be lower if the prepreg were cut and laid up under high relative humidity RH.

Incorrect formulation can also lead to a low T. In addition, if temperatures higher than cure or postcure were experienced in service, Tg could be increased.

Incorrect formulation can also raise T. Thermal analysis is a family of techniques used for studying the thermophysical and kinetic properties of materials. Uses for polymers include monitoring the cure of thermosetting resins, measuring the degree of cure of the final product, studying crystallinity in thermoplastics, studying the compatibility of multiphase systems Ref 1, 2 , and identifying transitions imposed upon the polymer by faulty processing or aging Ref 1.

Differential scanning calorimetry and TMA are simpler, lower-cost methods compared with the others. These techniques monitor the resin-curing process or determine the degree of cure of the finished product either by measuring the increase in T as cure advances, or by a technique-specific measurement of the curing reaction g itself e. However, the low-energy T signal that is easily observed by DSC or g TMA in a polymer-matrix, laminate, or a lightly filled composite may be difficult or impossible to detect in conditions of high humidity or in a highly filled composite of the same polymer due to the damping effect of the fillers.

Dynamic mechanical analysis, however, should easily detect the same T , since it offers nearly two g orders of magnitude of additional sensitivity over DSC to this measurement. Differential scanning calorimetry is the most popular thermal technique for polymer characterization. Differential scanning calorimetry has been used to study thermodynamic processes glass transition, heat capacity and kinetic events such as cure and enthalpic relaxations associated with physical aging or stress Ref 1.

Differential scanning calorimetry is commonly used to measure the T of uncured prepregs and cured laminates, g advancement in cured laminates, and also the degree of cure of the final product, the heat of reaction during prepreg processing, and relative resin reactivity. The degree of cure is determined either by the increase in the Tg with cure, or by measurement of the heat evolved from the curing reaction.

Figure 1 shows an example of both techniques in a comparison of an undercured and an optimally cured epoxy resin system for a given end use. The Tg shift with advance in cure is evident, while the residual cure is directly quantified. If not, relative degrees of cure can also be assessed. Graph shows advancement in Tg and measurement of heat of reaction. Curves rescaled and shifted for readability As mentioned previously, detection of the Tg by DSC may prove difficult or impossible in highly filled composites or where moisture is present.

In filled composites with reactive resin matrices epoxy , the heat of reaction is usually sufficient for comparisons to be made of degree of cure. However, quantitative accuracy can be affected by variability of fiber and filler content in the small samples used.

Modulated DSC, a high-performance version of DSC, improves the possibility for Tg detection because it can offer a fivefold increase in sensitivity over DSC and with no loss in signal resolution Ref 3. This allows direct analysis of the effects of aging or process-induced stresses, which appear as an enthalpic relaxation that can mask the T , with the net result being a signal that looks like an endothermic melt. The total heat flow g signal is shown in Fig.

Modulated DSC can resolve these overlapping events; the actual Tg of the epoxy composite appears in the upper curve in Fig. Upper curve: T ; lower curve: g g enthalpic relaxation Thermomechanical analysis determines dimensional changes in a material as a function of temperature or time under a controlled atmosphere.

The primary applications of TMA to thermosets are the measurement of both T and the changes in its coefficient of linear thermal expansion CTE with cure. Figure 4 shows measurement of the expansion coefficient and the Tg in a printed circuit board PCB laminate, where the signal is affected by an enthalpic relaxation effect due to stress induced by processing lower curve.

Annealing the sample removes the relaxation and allows clear detection of the glass transition upon reanalysis upper curve. Dynamic mechanical analysis measures the stiffness modulus and damping of a material as a function of temperature, time, and frequency under a controlled atmosphere. Multiple clamping systems allow operation in a variety of measurement modes single and dual cantilever, three-point bending, shear, compression, and tension on a range of samples.

Its high sensitivity makes DMA an ideal tool for following the course and kinetics of the cure process and for analyzing the viscoelastic properties of the final product. Dynamic mechanical analysis can detect some or all of the events in a thermoset curing cycle, including initial Tg of the uncured resin, the temperature of minimum viscosity, the onset of gelation, the cross-linking reaction, the cure completion, and the modulus of the fully cured material.

The sharp increase in the shear modulus with cure in Fig. Cross-linking reaction indicated by sharp increase in shear modulus. Frequency: 1 Hz; amplitude: 20 m Dynamic mechanical analysis is also used to measure the Tg of a cured material versus a target value and in relative-cure comparisons.

Its very high sensitivity to Tg detection is valuable in samples where the Tg is inherently weak or reduced by the presence of moisture or fillers. Absolute modulus numbers both below and above the T can easily be obtained.

The higher the modulus above the T , the higher is the degree of cure, g g while in comparative situations, the higher the T , the greater is the degree of cure.

In analyzing composites by g DMA, the sample should be loaded in a resin-dominated direction. In fiber-dominated orientations, the superior fiber stiffness controls the composite stiffness and masks the effect of the resin.

Dielectric analysis measures dielectric properties of a material as a function of temperature, time, and frequency under a controlled atmosphere. Permittivity dielectric constant is related to the ability of a material to store energy, while loss factor describes its conductive nature and is composed of two factors: energy loss associated with time-dependent polarization and bulk conduction.

The former dominates below the T , and the latter above it, due to ionic mobility Ref 4.Shipping fees are non-refundable. In addition, as printing plate-fountain solution interaction is influential for the printing quality, one should define fountain solutionb optimal chemical composition, for which measurements of pH value, electrical conductivity and surface tension are needed.
