Abstract
An uncured composite product having a middle fibrous reinforcement, a thermosetting-resin based layer and a hardening-agent based layer for the thermosetting resin. The thermosetting-resin based layer is placed on one side of the fibrous reinforcement and the hardening-agent based layer is placed on the other side so that the fibrous reinforcement forms a physical barrier between the thermosetting resin and the hardener. When heated, the thermosetting resin and/or hardener flows across the physical barrier to provide mixing and resultant curing.
