Epoxy binders are widely used as matrices for polymer composites (PCM) with a variety of reinforcing elements. However, the main disadvantage of epoxy binders and, consequently, PCM based on them, is low crack resistance and poor impact characteristics. To solve this problem, thermoplastics and highly dispersed nanofillers are used as modifiers for epoxy matrices. Despite the promise of this approach, homogeneous dispersion of fillers remains one of the main problems. The presence of functional groups in the modifier can affect the speed and completeness of epoxy group reaction. The purpose of this work is to investigate by FTIR spectroscopy the effect of a dispersed filler and a thermoplastic modifier capable of partial or complete dissolution in the epoxy oligomer-hardener system and of interaction with the hardener on the curing of the epoxy oligomer.
