– Temperature and pressure monitoring by multi-point sensing
– Micro-crack detection by AE methods
– Composite structure evaluation

Case 1

Strain distribution measurement of airplane wing

We embedded FBG sensors inside structural wing and measured 0.6mm resolved strain.

Strain distribution measurement of airplane wing

Case 2

Composite material tank pressure test

In a pressure test of a composite material tank (a barrel-shaped tank with a diameter of approximately 1 m and a length of approximately 2 m), an optical fiber strain sensor was installed at the position that supports the load, and the strain distribution was measured and evaluated with a spatial resolution of 1 mm.
