| Abstract: | A study on the modification of carbon/phenolic composites by means of adding nano-carbon black was carried out.The measured results on pyrolysis properties of phenolic resins containing nano-carbon black,ablative properties, thermal and mechanical properties at ambient temperature and interlaminar shear strength of charred materials show that the properties of the material are improved at different content,in particular, the interlaminar shear strength and the thermal expansion properties are improved remarkably. |
