CNT Enhanced Composites

Improved Strength, Toughness & Fatigue

Overview

The work by MIT Solutions exhibits a practical method to enhance the interlaminar shear strength by depositing a thin layer of electrospun epoxy or reinforced epoxy fibers in between the pre-impregnated composite. It can be more efficient in increasing its mechanical strength as it provides a large volume to surface ratio with porosity and forms interlayer bonding which help achieving the interfacial toughening effect and short beam shear strength.
