| Abstract: | Ultrasound waves are used to measure the concentration levels of mica and glass, simultaneously, in polypropylene polymer
compounds. A test chamber was designed to accommodate a 1 MHz ultrasound transducer for static calibration of the system response
to various levels of glass and mica concentration in the polymer blend. Temperature and pressure calibrations of the transducer
response were also performed under controlled experiments. Attenuation and time-of-flight measurements of ultrasound waves
propagating through the polymer blend were used to determine the relative concentrations of the fillers. The experimental
results show that the system is capable of measuring the filler concentration of mica and glass fibres within _0.5% and _1.0%, respectively. |
