Abstract: A part made of a fiber-reinforced composite material includes a structure made from a set of fibers supported in a thermosetting resin and a peel ply across all or part of the outer surface of the structure. The part has a gradient of polymerization at the interface between the structure and the peel ply. Also, methods for making such a part and methods for bonding such parts.

Abstract: A wide area data carrier network is described comprising: one or more access networks; a plurality of server units housed in a server module and installed on said wide area data carrier network so that each server module is accessible from the one or more access networks, the server module being adapted so that it may be located at any position in the wide area network; and an operations centre for management of the server module, the server module being connected to the operations centre for the exchange of management messages through a network connection. The server module comprises at least one server card insertable in the server module, the server card having a central processing unit and at least one rewritable, non-volatile disc memory device mounted on the card. Preferably a local management system is provided in each server module capable of receiving a command from the operations centre and for executing the command to modify a service performance of at least one server unit.
