Mechanical Properties of Polybenzimidazole Reinforced by Carbon Nanofibers
Polybenzimidazole (PBI) and vapor grown carbon nanofibers (VGNFs) nanocomposites were developed successfully by using ultrasonic mixing followed by hot compress. The contents of VGNFs used were 0.5wt%, 1wt%, 2wt% and 5wt%. The mechanical properties of neat PBI and PBI/VGNFs nanocomposites were discussed and the results were that the Young’s modulus, tensile strength, storage modulus and hardness were improved after adding VGNFs. Microscopic analysis showed that the dispersion of VGNFs in nanocomposites with a lower amount was considered to be uniform.
