L-shaped carbon fiber reinforced plastic (CFRP) laminates were designed and fabricated for application in lower limb orthosis. Four types of CFRP laminates were constructed to attain a bending moment of 10 Nm at 5° rotation. Bending tests were conducted on the laminates using a newly developed testing fixture. Further, acoustic emission (AE) measurements were conducted during these tests to characterize the microscopic damage behavior in the laminates. It was confirmed that the laminates designed in this study have an appropriate stiffness that supports walking. Moreover, microscopic damage behaviors were well-characterized to monitor the rise time and duration of AE waves.
