• epoxy–graphene nanocomposites. In addition, almost in all cases, the nanocomposites were produced using solution casting. Therefore, solution casting and thermosetting epoxy are still the favorite synthesis methods. The first report about the preparation of aligned CNT–polymer composites was published

The addition of CNTs as secondary reinforcement in glass fiber-based polymer composites can significantly improve the resistance against cyclic delamination and crack propagation. The inter-laminar fracture toughness also improves due to the deflection of the cracks by

There are many concepts that describe the interaction between polymers and nanoparticles, of which the most popular are two theories on the formation of nanoparticle–polymer composites. The first theory involves the in situ synthesis of nanoparticles as a result of precipitation reactions of
