Abstract
A fiber-reinforced composite laminate for use in electromagnetic welding of molded parts of said laminates. The laminate has a plurality of structural layers, each formed of electrically conductive fibers embedded in a thermoplastic matrix. Eddy currents may be induced in the electrically conductive fibers by an electrical conductor that generates an electromagnetic field. The structural layers include a first, a second and, optionally, a third pair of two adjacently positioned structural layers. The first pair has an intermediate layer which allows eddy currents to flow between the two structural layers of the first pair. The second pair has an intermediate layer which prevents eddy currents from flowing between the two structural layers of the second pair. The optional third pair does not have an intermediate layer. The laminate shows efficient heating by an electromagnetic field.
