Abstract

Nowadays, it is vital to predict strength results of composites in advance of manufacturing process to reduce testing costs; especially in carbon nanotube (CNT) reinforced metal matrix composites. Therefore, compressive mechanical properties of fabricated CNT reinforced aluminum (Al) matrix composites are investigated and compared with the calculation results of dispersion based prediction models. First of all, CNT/6063 Al composites are fabricated by vacuum assisted infiltration of molten 6063 Al alloy into the CNT preform. Then, compressive mechanical properties of these composites are determined. Eventually, model calculations and experimental results are visualized by plotting comparison graphs. As a result, correlation between prediction models and experimental results are established and potential results of difference between these results are discussed.
