Fiber agglomeration

Figure 6-11. Fiber agglomeration contour lines as a function of the deposition temperature and MTS flow rate for two fixed hydrogen flow rates show the strong influence of MTS flow rate and temperature on agglomeration and the smaller influence of hydrogen flow rate.

Figure 6-12. Plot of fiber agglomeration versus coating thickness shows the trend of increased agglomeration with increased thickness.

Based on a rectangular model assumption of the glass fiber/pol3nner fiber agglomerations, the following equation can be used to calculate the necessary impregnation time (f) in order to achieve a void content which is lower than a certain limiting value ... 

Figure 12.17 shows the formation process of such a pill. In the beginning, single fibers are more or less dragged out of the textile (a, b). Then after further friction is applied, the fiber ends form loops (c). Cloud-like fiber agglomerations are formed (d), and finally, the fibers can form knot-like structures (e). This knot is connected to the textile surface by a single fiber, the so-called anchor fiber.
