The so formed composite material is machinable and suitable for automated production.
Another possibility to follow chemical changes during the crosslinking process is to apply Raman spectroscopy. [3, 4, 7] In Raman spectroscopy the interaction of a laser and the examined sample is used to monitor the chemical structure or the composition of materials.
