Overview

Randomized trial improves mechanical properties and self-sensing in basalt fiber composites, indicating potential for smart structures.

Key Points

  • This study aims to enhance the mechanical properties and damage detection capability of basalt fiber reinforced epoxy composites by utilizing reduced graphene oxide.
  • Constructed a wrinkled reduced graphene oxide (rGO) interface using electrophoretic deposition (EPD) and thermal reduction.
  • Conducted mechanical characterization to assess improvements in flexural and tensile modulus after modification.
  • Performed finite element analysis (FEA) to evaluate the impact of the thickened interface on interfacial stress.
  • Flexural modulus increased by 52% and tensile modulus by 105% in rGO-modified composites.
  • Surface roughness increased from 38.2 nm to 182.9 nm; maximum interface thickness increased from 99 nm to 384 nm (288% increase).
  • Modified composites demonstrated excellent damage self-sensing with gauge factors of 102.5 under tensile, 176.4 under compressive, and 59.7 under flexural loading.
