Comparison of Young’s Moduli Determined by Impulse Excitation Technique (IET), Dynamic Mechanical Analysis (DMA) and Tensile Test (TT)
Original language description
To investigate elastic and viscoelastic mechanical behavior of glass bead reinforced thermoplastics, two composites were tested with Impulse Excitation Technique (IET), Dynamic Mechanical Analysis (DMA) and Tensile Test (TT). 3 point bending DMA tests of neatPolyamide 66 and Poly(butylene terephthalate) as well as their composites (30/40 wt-% and 20/30 wt-%, respectively) were performed in the temperature range 20 to 200 °C for the frequencies 1, 2, 5, 10, and 20 Hz. The theory of Williams, Landel and Ferry (WLF) allows forcomparison of bending moduli of frequency dependent “destructive” DMA measurements to non-destructive IET measurements in flexural mode by determining the eigenfrequency of the specimen at room temperature. Similarly, moduli of IET in longitudinal mode were comparedto Young´s moduli of TT at strain rates of 1, 10, and 100 %/min. Both comparisons provide moduli agreeing well with respect to standard deviations. Furthermore, a cube in cube modelapproach was used to model interfacial adhesion effects and to calculate reasonable adhesion coefficients kadh for the different measurement techniques.
