Structural Health Monitoring

Overview

AMAC's research focuses on integrating cutting-edge sensing technologies into composite structures to enable real-time monitoring and damage detection. A notable project involves embedding distributed optical fibre sensors (DOFS) within composite materials. These sensors facilitate continuous assessment of structural integrity during both manufacturing and operational phases, allowing for early detection of potential failures. Another significant advancement is the use of fibre Bragg gratings (FBGs) for real-time measurement during Automated Fibre Placement (AFP) processes. This approach not only monitors the manufacturing process but also provides lifelong health monitoring of composite parts, ensuring their reliability in various applications.

AMAC's SHM technologies have been applied to the development of shape-adaptive composite hydrofoils for marine vessels. By integrating fibre optic sensors, researchers can monitor strain fields within these structures, enhancing their performance and safety. AMAC's work with the Defence Science and Technology Group focuses on optimising composite structures for defence applications, including the design and manufacture of advanced composite hydrofoils using AFP technique. AMAC collaborates with various industry partners to translate research into practical applications.
