The composite materials have been expanding their application field in aircraft industries taking the advantage of their excellent mechanical properties such as high specific stiffness and strength. At present, the composite materials are come to use not only as thin plate shells but also as thicker strength members. But the failure and fracture process and property of the composites are complicated comparing with usual metallic materials. This paper presents a method to monitor some mechanical behaviors and conditions at composite joint portions using a strain sensor embedded into fastener bolt. This method enables us to grasp the information related to the structural integrity at joint portions online. In this report, the basic principles of the measurement system are shown by numerical calculations for elementary models.
