Abstract: In this paper, the application of the composites of carbon nanotubes (CNTs) reinforced thermosetting resins including epoxy resin (EP), phenolic resin (PF), bismaleimide resin (BMI), and cyanate resin (CE) was introduced, The recent development in research of these composites was reviewed. The inclusion of CNTs improved the mechanical, thermal, and frictional properties of the thermoset matrix. The measures to improve the dispersion of CNTs in epoxy resin and bismaleimide resin were presented. The present problems and development prospect of thermosetting resin/CNTs composites were also discussed.

Key words: thermosetting resin, modification, composite, carbon nanotube
