Area of Science:

  • Materials Science
  • Mechanical Engineering
  • Composite Materials

Background:

  • Shape memory alloy (SMA) tufted composites enhance mechanical properties like strength and fracture toughness in structural joints.
  • Self-sensing capabilities are crucial for real-time structural health monitoring.

Purpose of the Study:

  • To investigate the self-sensing functionality of SMA tufted carbon/epoxy composite T-joints.
  • To enable in situ strain monitoring for detecting low-velocity impacts.

Main Methods:

  • SMA tufted carbon/epoxy composite T-joints were subjected to low-velocity impact tests (5 J and 10 J).
  • An Arduino Mega controller was used to record real-time electrical resistance changes in SMA tufts.
  • The system was designed to trigger upon abrupt resistance changes caused by impact-induced deformations.

Main Results:

  • The SMA-enabled detection system accurately captured the timing of impacts.
  • The system successfully localized the onset of delamination.
  • Abrupt changes in electrical resistance of SMA filaments correlated with impact events.

Conclusions:

  • SMA tufted composites possess multifunctional capabilities for structural health monitoring.
  • The proposed system demonstrates effective real-time detection and localization of impacts and delamination.
  • This technology holds promise for advanced damage detection in composite structures.
