Buckling compression behaviour of CNT engineered composites

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 determin...
