Development of Epoxy-Based Binders and Triethylenetetramine (TETA) Modified with Thermoplastic Polyurethane

For the first time, binders have been developed for creating composite materials by contact molding, including ED-20 epoxy resin and triethylenetetramine modified with thermoplastic polyurethane. For cured binders, compared to an unmodified sample, the abrasion resistance index increases by 2.3 arb. units. Glass-reinforced plastics manufactured using the developed binders are characterized by increased values of bending stress at maximum load and elastic modulus up to 522 MPa and 16.0 GPa, respectively.
