description |
Research has shown that Carbon Nanotubes (CNT) have exceptional mechanical
properties and show promises as a reinforcement for high performance composites. In
this work, CNT was added to Carbon Fibre Reinforced Plastic (CFRP) composites, and
collectively placed under compression tests to determine their buckling behaviour.
For a start, CNT was dispersed in ethanol and dried before its transfer to the middle
layer of multiple CFRP strips joined together. The resulting specimen was then cured
and placed under axial compression, with its buckling loads and respective deflections
measured. The conditions were then varied, such as the modification of CNT and CFRP
quantities and the use of a curing table over the autoclave. These served to reinforce the
results and conclusions.
From the data recorded, it was found that the elastic modulus of the composite increased
with CNT concentration, indicating that CNT improved the buckling resistance of the
composite. However, there is a limit to CNT addition and the optimum concentration
was determined to be between 1 and 2g/m2. Future considerations could be made to
improve the dispersion of CNT with more active solvents, or utilising more accurate
equipments in data acquisition. |
