Discussion and Data Analysis
The mass of the samples has been determined gravimetrically before and after the experiments with a semi-microbalance (reproducibility: 0.015mg).
At least a reduction of the possible effect of funding active structures can also be expected.

Up to a maximum load of crack opening the resistance increases (in contrast of its reduction for the sample without crack).
Reactance of predicted and measured EMI as function of tensile load It can be seen that the predicted magnitude and reactance are close to the test data.

This is in well agreement
with the results from the microtensile tests, i.e. a significant reduction in the value of modulus for
the CNT containing samples compared to the reference one.
Note that the scale for the pure copper REF2-ABC is on the right side of the graph while the scale for the reinforced materials is on the left The method for measuring the thermal conductivity turned out to be reliable and accurate, as the thermal conductivity of the reference sample REF2-ABC at room temperature was estimated to be 403 W/mK (Fig. 5) and which corresponds quite well with data from literature for pure copper.

Since resin absorbs water by aging in high temperature and high humidity conditions, the reduction in the peak strength at 1296 cm-1 seems to be caused by water absorption reaction.
Furthermore, dispersion of plotted data was seen in the relationship between Dw and the tensile strength in the latter period in aging at the temperature over Tg.

Pulse electroplating of Zn–Fe coatings resulted in the grain size reduction to 50 nm at Jp 0.2 A cm-2.
XRD spectra for Zn-Fe alloy coatings by PC deposition J-60-9 and by RPC deposition J-60-9(30:8) The influence of pulse parameters on the phase composition of the deposited alloys can be determined from XRD data.
