Core aerospace engineering and protocols for Fiber Optic Strain Sensing.
Unlike aluminum airframes where fatigue manifests as visible surface cracks, carbon-fiber composite materials can suffer internal delamination and sub-surface core crushing without any outward cosmetic blemishes.
AirplaneTwin integrates hair-thin optical fibers embedded directly between composite plies during manufacturing. Fiber Bragg Grating (FBG) sensors measure micro-strain deflections along the entire wing span during flight, detecting internal structural stress long before mechanical failure occurs.
