“…Ultrasonic test is a valuable non-destructive tool for determining the integrity of porous materials [17]. Ultrasonic equipment works by generating input signals using an emitter transducer, which are received by a receiver transducer placed on the sample surface [18]. In this study, direct test through the membrane sample was used, where the emitter and receiver transducers are in a straight line on opposite sides of the membrane tested.…”

“…Thus, in year 1991, Sztukiewicz [9] publishes paper on the possibilities of applying ultrasonic methods in asphalt concrete testing concluding that this method can be useful in highway sufficiency rating. Tagdemir et al [10] investigate possibilities of applying ultrasonic methods in asphalt concrete specimen testing in order to estimate its fatigue life. Results of this study indicated that only by examining the ultrasonic method it will be possible to predict the fatigue lives of the asphalt concrete specimens non-destructively, creating possibility of method application also in other pavement materials.…”

Original scientific papers Performance of ultrasonic pulse velocity (UPV) in hydraulically bound mixtures is examined as a non-destructive testing, in order to estimate its potential for pavement material characterization. Test results show that an increase in cement content results in an increase in UPV values. Increase in steel slag aggregate content results in a decrease in UPV values. Analyses of relationship between UPV values and strengths have shown strong polynomial relationship. For UPV values ranging 2 ÷ 3,2 km/s cement stabilized material can be classified as appropriate for usage in road construction. Test results have shown good potential for UPV measure as non-destructive method in cement stabilized material characterization.

“…The processes for conventional imaging with SEM typically have complex processes for preparing specimens to allow specimens having electrical conductivity on the surface. On the other hand, ultrasound technologies have been used for non-destructive testing [3][4][5], in which ultrasonic pulse-echo method is frequently applied to measure the internal structure and mechanical properties of materials [6]. To better detect the fine structure of a polymer composite, the frequency of ultrasound has to be increased to provide better spatial resolution for measurement.…”

Conductive polymer composites fabricated by adding a certain amount of conductive fillers, such as carbon black or carbon nanotube, into a polymer substrate are commonly used as the material of the bipolar plate in fuel cells. The electrical conductivity of polymer composites is affected by the distribution and orientation of fillers and is therefore crucial to be assessed. This study is to develop methods and techniques for nondestructively measuring properties of carbon fibers in the conductive polymer composite using a high frequency ultrasound system. The experiments were carried out from samples, fabricated by an injection molding machine, composed of a 5x5 cm polycarbonate added with carbon fibers of 6 μm diameter and 3 mm length and those of weight percentage at 0, 0.1, 0.2, and 0.3%. The ultrasonic signals of conductive polymer composites associated with different filler concentrations were acquired from a 48 MHz high frequency ultrasound imaging system. The raster scanning images corresponding to depths at 0.15 and 0.3 mm beneath the surface of conductive polymer composites were reconstructed. The orientation of filler carbon fibers parallel or perpendicular to the surface of conductive polymer composites were calculated according to their respective percentages of pixel content in the image. Results showed that percentages of pixel contents for fillers of carbon fibers at the depth of 0.15 mm beneath the surface of sample for those 0.1, 0.2, and 0.3 wt% filler carbon fibers were calculated to be 2.50±1.13, 5.19±1.70, and 5.93±1.29, respectively, and those of 0.3mm were to be 2.91±1.46, 6.18±1.60, and 6.42±1.77, respectively. Moreover, those percentages of pixel contents for fillers of perpendicular orientation with respect to depth of 0.15mm were 1.49±0.89, 2.49±0.96, and 3.62±0.95, respectively; those of 0.3mm were 1.39±0.72, 2.70±0.62, and 3.97±0.94, respectively. This study demonstrated that current high frequency ultrasound image incorporated with the analysis method is feasible to be applied to quantitatively and rapidly assess the distributions of fillers in conductive polymer composites.
