Method & Evidence

AimTo investigate the impact of multi-walled carbon nanotubes (MWCNTs) on the tensile and compressive properties of epoxy-based composite materials and laminates.

MethodExperimental material characterization

ProcedureSix different composite materials were fabricated: a pure epoxy control, a MWCNT-reinforced epoxy, and four types of glass fiber reinforced epoxy laminates (two quasi-isotropic and two unidirectional), with and without MWCNT reinforcement. These materials were then subjected to standardized tension and compression tests to determine their mechanical properties.
