Description
Carbon nanotubes (CNTs) because of their properties are alleged to be the key candidate additives for improving the mechanical properties of polymers and carbon fibre reinforced polymers (CFRPs). Nevertheless in order for the reinforcing effect of the nanotubes to be of practical use, the CNTs have to be mixed with the matrix material In Me current work an effort was made to chemically graft Multi-Wall Carbon Nanotubes (MWCNTs) on the actual reinforcing Carbon Fibres (CFs) in order to skip the sometimes complex mixing stage. Two different solutions were used in order to treat/prepare the CNTs; a) an acid solution of H(2)SO(4)/HNO(3), and. b) a toluene solution. The treated CFs were added to each solution, sonic bathed with deionised water and Own dried in an oven. The resulting CFs were examined under SEM and both the solutions used proved to) be reasonable successful with further investigations/optimisation to be necessary.
