Properties Of Glass Fibre Epoxy Laminated Composites With Electrospray Of Different Carbon Nanotubes Concentrations

Laminated composite materials are used extensively in aerospace and other applications due to their high specific modulus and high specific strength. However, interlaminar fracture or delamination damage is the challenge in laminated composites. Therefore, the aim of this study is to improve the int...
