»Theorizing that pristine graphene may be a better additive than CNTs and GO for PAN-based carbon fibers, researchers added a small amount of shear-exfoliated pristine graphene (0.01 to 1.0 wt %) to a PAN/dimethyl sulfoxide solution to fine-tune the properties of the PAN spinning dope. Results showed that PAN/graphene-based carbon fibers with 0.075 wt % graphene exhibited a tensile strength of 1916 MPa and Young’s modulus of 233 GPa — a 225% increase in strength and 184% increase in modulus compared to PAN carbon fibers without graphene.»

Many works have reported the effect on the mechanical, thermal, and electrical properties of fiber composites reinforced with nanotubes and graphene-based materials.

This Ashby plot (yes, we love them!) of Young’s modulus vs. Tensile Strength compares the mechanical properties of natural fiber-based polymer composites with glass fiber reinforced plastics (GFRPs), carbon fiber reinforced plastics (CFRPs), carbon nanotubes (CNTs), and graphene-based polymer composites.

It is crazy to think that any newly discovered material can generate many other composite materials! That is why composites are so fascinating!
