Pilot winding of three batches of fiberglass rods was carried out on the production line. The optimal composition of the EDI binder was selected with the ratio of the components ED-22 / IMTGFA / UP-606/2 in mass parts: 100/85 / (1.5 - 3), which provides an increase in the glass transition temperature of products by 10 - 15 & # 176; С compared to control samples. The increase in the glass transition temperature was confirmed by TMA and DSC methods in all three pilot batches, manufactured at different times. Temperature conditions for processing a new composition of EDI in an impregnating bath 35 and 40 & # 176; C are proposed to increase the viscosity, which ensures the mass content of the binder in fiberglass 15 & # 37; that meets the requirements of regulatory documents
