Abstract

Post-curing of GFRP based on a bismaleimide binder was carried out by varying the post-curing temperature and time. The thermophysical properties of the material were determined by DSC and DMA methods. The mechanical properties of the material were determined by flexural and interlaminar shear strength (ILSS) tests. The shift of curing reaction peak, visual changes in the material, and changes in its mechanical properties with the increase of the curing temperature and time were studied. Recommendations for selecting the operating temperature of the material and proposals for further research are provided.

Keywords
