摘要

Multi-axis fiber grating strain sensors have been used to quantitatively measure axial strain and temperature; transverse strain and transverse strain gradients in composite weave structures. This paper overviews the multi-axis fiber optic grating strain sensors and how they can be applied to measuring multidimensional strain fields interior to composite parts with complex composite weave structures. Experimental results are given for the case of a bi-axially woven composite coupon as well as for an E-glass/epoxy composite sample.
