increase the interlaminar bond strength in one practical embodiment titanium alloy metal sheets may be used which each have a thickness of approximately 0 0025 inches the film adhesive 45 may be approximately 0 005 inches thick and four composite carbon fiber epoxy plies 35 may be used in each layer 38 having a collective total thickness of about 0 30 inches depending on the application the use of metals other than titanium may be possible the distance between adjacent transition points 39 and thus the length of the overlap between the layers 38 as well as the thickness and number of composite plies 35 and the thickness of the metal sheets 37 will depend on the requirements of the particular application including the type and magnitude of the loads that are to be transmitted through the joint 26 and possibly other performance specifications it should be noted here that the bonded metal sheets 37 is not limited to use in a composite metal joint 26 discussed above as will be discussed later below a metal structure comprising bonded metal sheets 37 has a variety of other applications because of the superior strain performance it may exhibit compared to monolithic metal structures the differing layers 38 of the joint 26 between the two differing materials of the composite and metal portions 22 24 respectively fig1 render the structure 20 well suited to nondestructive evaluations of bond quality using embedded or mounted sensors not shown ultrasonic structural waves not shown may be introduced into the structure 20 at the edge of the metal portion 24 at the composite.
