- Аннотация: Composites consisting of propargyl- and allyl/propargyl- modified novolac resinsand carbon fabric were obtained by the vacuum infusion molding process. It wasestablished that the presence of potassium cations remaining after the synthesisincrease the resin melt viscosity, and acid washing is needed to obtain resinssuitable for cost-effective injection techniques of composite fabrication. Themechanical properties of all composites such as compressive strength, tensilestrength, in plane shear strength, and interlaminar shear strength were determinedat 25, 200 and 230 °С. The carbon fiber reinforced plastics (CFRPs) retained theirmechanical properties at temperatures up to 200 °C. It was shown that the use of theobtained allyl-containing polymer matrices improved mechanical properties andincreased the thermal stability of the CFRPs in comparison with the propargylatednovolac matrices. The composite material with novolac matrices modified by 18%propargyl and 23% allyl groups retains only up to 70% of the initial inter laminarshear strength values at 230 °C which corresponds to the data of the dynamicmechanical analysis of neat cured resins.
