30. Note that the azimuthal trace for the 47 wt % fiber composite in Figure 6 was extracted from the data of Figure 1, where the peak which is asterisked in Figure 2 is not visible. This is because the ratio of α to γ material in Figure 1 is much greater than in Figure 2, so by choosing an intensity gray scale that highlights the α-iPP reflections for Figure 1, the weak γ-iPP reflection disappears into the background.
