Glass Fiber Reinforced PBT — Dynamic-Mechanical Properties
A 30% glass fiber-reinforced PBT (parallel and perpendicular to the fiber orientation) was measured in the 3-point bending mode at 1 Hz and 2 K/min.
Considerably higher values for the stiffness and the onset of the E'-decrease (43°C) are obtained for the parallel-oriented type (solid line). The tanδ values are accordingly lower. The tanδ peaks are at the same temperature.
