Article Synopsis
- New fiber Bragg grating (FBG) sensor probes are developed to measure the maximum tensile strain in composite materials for structural health monitoring.
- The probes consist of thin aluminum films attached to FBG optical fibers, which capture residual strains that reflect the composite materials' strain levels.
- Two sensor types are tested with different aluminum thicknesses (18 μm and 36 μm), revealing that the 36 μm probe has higher strain sensitivity (0.23) compared to the 18 μm probe (0.13).
